At a glance: requirements & format
Sourced from the University of Washington School of Dentistry's own UWIDDS admissions pages — including the 2026 IDDS FAQ and the Interview/Skills Testing page — and the ADEA CAAPID program listing (last updated February 9, 2026). Confirm anything decision-critical with the IDDS program office at idds@uw.edu before you spend money.
- Doctor of Dental Surgery (D.D.S.) from a CODA-accredited program; graduates are eligible to take state or regional board examinations for US licensure
- 30 months — 10 full-time quarters, winter-quarter entry, integrated into the predoctoral clerkship model with classroom lectures and direct patient care
- 20 seats per cycle (ADEA CAAPID estimate); UWIDDS states that only a small number of students are accepted each year
- March 5, 2026 — every applicant, first-time or returning, must apply through ADEA CAAPID; UW accepts no direct applications
- June 1, 2026 — incomplete applications are not reviewed by the IDDS Admissions Committee, and late or updated documents are not considered
- File reviews begin in April 2026; interview invitations are issued between May and June 2026, after the program processes your CAAPID release
- Yes — a three-day skills/interview session covering restorative, endodontic and fixed prosthodontic procedures on manikin and plastic teeth, plus a written case-based exam, graded blindly
- Interviews with selected faculty during the same three-day session (June–July 2026), open-file in practice; UW does not publish panel size or interview length
- Required with no waivers for anyone whose dental degree is from outside the US — 100 or higher for exams before January 21, 2026, or 5.00 or higher after; no Home Edition, no MyBest, test must be within two years, report submitted directly to CAAPID
- Pass the INBDE, or NBDE Parts I and II; official reports go through ADEA CAAPID, results more than five years old are still accepted, and your file is not forwarded for review until scores are uploaded
- Course-by-course comprehensive evaluation from ECE or WES only, uploaded to CAAPID directly by the evaluating agency
- Three, submitted only through CAAPID — English, on letterhead, signed, written within the last 12 months, addressing your strongest and weakest characteristics and your class ranking where possible
- None — UWIDDS has no supplemental application and asks that no supplemental materials be sent; a CV using UW's mandatory template is uploaded instead
- $185, non-refundable, paid through the UW School of Dentistry electronic payment portal; email the receipt with your full name and CAAPID ID in the subject line to idds@uw.edu
- A non-refundable dental skills testing fee is required of applicants invited to the bench phase, payable when you accept the interview invitation and not applied toward tuition — request the current amount from idds@uw.edu
- Admission status notifications are sent in August 2026; accepted applicants reply to the offer letter with a non-refundable $5,000 deposit that is not applied toward tuition
- Classes begin in January 2027 at the winter quarter; mandatory orientation for admitted students is held in December 2026
- UWIDDS Program Office, University of Washington School of Dentistry — idds@uw.edu for requirement questions, application status, and to request an advising appointment
Requirements change — verify before you spend money
The bench testing fee, the payment portal steps, and the TOEFL scoring band are revised between cycles — UW moved to the 5.00 scale for exams taken on or after January 21, 2026, and the skills testing fee is not published on the admissions pages. Before you pay the $185 fee, book a test date, or buy flights to Seattle, email idds@uw.edu and confirm the current requirement in writing for the cycle you are applying in.
How the UWIDDS evaluation actually works
Washington runs a long-file, short-visit model: months of document screening decide who gets to Seattle, and then a compressed three-day session decides who gets in. The order matters because the file review is pass/fail — an incomplete CAAPID record is never scored — while the three-day session blends two instruments the committee reads together: a blind-graded psychomotor bench examination and faculty interviews held in the same building in the same week. Prepare them as two separate projects.
-
1
Stage 1: The CAAPID file review — the gate before Seattle
The University of Washington opens its CAAPID application on March 5, 2026 and closes it on June 1, 2026. Because UWIDDS runs no supplemental application, everything the committee will ever read about you has to arrive through ADEA CAAPID: the course-by-course ECE or WES evaluation uploaded by the agency, the INBDE or NBDE Parts I and II report, a TOEFL iBT score taken within the last two years, three letters of evaluation, and a CV built on UW's own required template. A $185 non-refundable application fee goes to UW's electronic payment portal, and you email the receipt with your name and CAAPID ID to idds@uw.edu.
File reviews begin in April and the program warns that your status confirmation can take up to four weeks after ADEA releases your application. What this stage measures is completeness and paperwork discipline, not talent. UW states plainly that incomplete applications are not considered or reviewed, that only the three letters you submit through CAAPID are accepted, and that updated documents sent directly to the program office are turned away. No score rescues an unread file.
Five procedural traps that kill an application
Use UW's CV template — your own format is not what was asked for. Email the payment receipt to idds@uw.edu, because nothing confirms it automatically. Ask recommenders to address your weakest characteristics and class ranking, not just praise. Keep letters under 12 months old. And do not mail transcripts yet — UW collects official transcripts only after you are admitted, and they become UW property.

Stage 2: The three-day session — orientation and faculty interviews
File review produces the invitations, which go out between May and June 2026, early enough that UW says it is deliberately accommodating travel from abroad. Invited candidates then travel to Seattle for a three-day skills and interview session: an orientation to the dental school, psychomotor assessments, and interviews with selected faculty. Interviews run through June and July 2026, with the bench examination window falling in July and August.
UW does not publish the panel size, the interview length, or whether the conversation is open or closed file, so treat the published structure as the contract and confirm the details in your invitation. In practice the session is read as open file, and candidates describe two one-on-one conversations of roughly 35 minutes each with faculty or committee members, sometimes virtual and sometimes on campus. That spread is the point of preparing for both formats: what the committee is grading here is whether the person in the room matches the file it already read and defended at review.
Re-read your own file the week before you fly
Open-file interviews start from your own materials. Refresh your personal statement, your CV (the UW template version, not your private copy), your research, your leadership and the framing in your three letters. Then prepare a two-sentence expansion for every distinctive item you listed — a mission trip, a practice you ran, a teaching role, a research project. The trap is answering a question about your own application vaguely because you wrote it a cycle ago.

Stage 3: The bench examination — blind-graded, on manikin and plastic teeth
This is the instrument that separates Washington from programs that only talk. Candidates must perform restorative, endodontic and fixed prosthodontic procedures on manikin and plastic teeth, plus a written case-based exam. UW provides all hand instruments, handpieces, plastic teeth and study models, communicates the requirements beforehand, and grades the end result blindly, exactly as it grades its regular courses — the outcome is explicitly part of the basis for acceptance.
The blind grading is the load-bearing detail. Nobody in the room can attach your name to your prep, so the only thing carrying your case is the tooth itself: taper, reduction, margin placement, finish-line quality, pulpal safety, and whether the work survives a grader who has no reason to be generous. That is why the skills session is ordered alongside the interviews rather than after them — the committee is comparing a spoken claim about your clinical ability with a physical object you produced under time pressure.
The testing fee is non-refundable and the date is fixed
UWIDDS charges a non-refundable dental skills testing fee to every applicant invited to the bench phase — payable at the moment you accept the interview invitation, and never applied toward tuition. The amount is not published on the admissions pages, so request the current figure from idds@uw.edu before you confirm attendance, and book refundable travel until your session dates are confirmed in writing.

Stage 4: Notification, the $5,000 deposit, and the winter start
Admission status letters go out in August 2026. If you are selected, you respond to the offer letter and include a non-refundable $5,000 deposit that is not applied toward tuition, then satisfy UW's credentialing and deposit conditions before anything else moves. Mandatory orientation for admitted students is held in December 2026, and classes begin in January 2027 at the winter quarter, running 10 quarters to the D.D.S.
Two financial facts belong in your planning now rather than in August. UW School of Dentistry has no scholarship program for incoming IDDS students, and federal financial aid is limited to US citizens, permanent residents and eligible non-citizens. Students on a visa must also submit a proof-of-financial-ability form to International Student Services showing funds to cover tuition, dental kit, books, living expenses and fees. Build that number before you are admitted, not after.
Count the full cost of the trip, not just the fee
The three-day session means flights, accommodation and time away from practice during the busiest stretch of the cycle. Treat travel as a budget line from the start, keep your passport and visa documents current, and confirm your session dates directly with idds@uw.edu before booking anything that cannot be changed.
What UW's IDDS Admissions Committee is really evaluating
Washington publishes requirements rather than a ranked rubric, so read these five criteria as the things the two-stage process is built to measure — each maps to a stage you can prepare for on purpose.
Manual dexterity under blind grading
The bench examination is graded without your name attached and forms part of the acceptance decision. Restorative, endodontic and fixed prosthodontic work on manikin and plastic teeth is scored the same way UW scores its own students — so drill US preclinical standards until they are reflex, not recall.
A complete file is the only entry
UW reviews complete applications only. No supplemental application exists, the three letters must arrive through CAAPID, updates sent to the program office are refused, and the file is not forwarded for review until INBDE or NBDE results are uploaded. Missing one item means unread, not penalised.
English proficiency with no exceptions
TOEFL iBT is mandatory for every applicant whose dental degree comes from outside the United States, including US citizens. UW waives nothing: no Home Edition, no MyBest scores, no exemption for a US degree earned along the way, and the test must be within the last two years.
Open-file credibility with faculty
Interviews with selected faculty sit inside the same three-day session as the skills assessment. The committee has your file and your letters in hand, so the test is consistency: does the person describing their clinical background match the record, and do the letters that name strengths and weaknesses line up with what you say out loud?
Readiness for a full-time clerkship
UWIDDS is a full-time, daily program that integrates you into the predoctoral clerkship model with lectures and direct patient care for 30 months. The committee is judging whether you can carry that load from the winter quarter onward — and whether you understand that Washington licensure runs through a DQAC-approved degree.
Washington IDDS interview questions (with coaching notes)
These prompts are grouped into the four things the UWIDDS process measures: your motivation, your behaviour under real conditions, your judgement when there is no clean answer, and the skills-day conversation that runs alongside the bench examination. Answer every one aloud — the interview is spoken, and so is the impression you leave in the simulation lab.
Motivational & background
4 questionsTell me about yourself and why you want to be a dentist.
How to answer
Build a 90-second arc: where you trained, what your clinical work looks like now, what pushed you toward US licensure, and why the UWIDDS 30-month pathway is the vehicle. The interview is open file, so the trap is reciting your personal statement word for word instead of narrating it with emphasis.
Why dentistry, and why pursue it in the United States?
How to answer
Anchor the answer in something concrete — US clinical exposure, a patient population you want to serve, a defined professional goal — and name the Washington licensure path through a DQAC-approved degree. 'Better technology' and 'a higher standard of care' are the two answers that sink candidates.
Tell me about the defining moment you decided on dentistry. One moment, not a series of events.
How to answer
Pick a single scene with a date, a place and a person, then say what changed in your thinking because of it. The prompt deliberately forbids a timeline, so a candidate who lists five influences has already missed the question — the committee is testing whether you can choose and commit.
Describe your ideal practice ten years from now.
How to answer
Give a specific trajectory — private practice in a defined setting, a specialty, public health, academia or a combination — and connect it to why you are entering the US system in this cycle. The trap is naming a specialty you cannot explain a path to; the committee is listening for a plan, not a title.
Behavioral
4 questionsTell us about a significant challenge in your life and how you overcame it.
How to answer
Choose one with real stakes — rebuilding a career in a new country, INBDE preparation, a hard clinical case — and spend the middle of the answer on what you actually did, not on how hard it was. Name the specific correction you made and where that correction shows up in your practice now.
Tell me about your leadership activities.
How to answer
Pick one role with a measurable outcome: a clinic you ran, a team you trained, a course you organised, a committee you chaired. Say what you decided, who it affected and what changed afterwards. Listing titles without consequences reads as resume filler and invites the committee to probe.
Tell us about your research experience.
How to answer
State the question you studied, your role, one finding in plain language, and what it taught you about reading evidence critically. UW students work with faculty in an academic health system, so a candidate who can explain their own project to a non-specialist scores better than one quoting their abstract.
Describe your experience with waxing, lab work, and manual dexterity.
How to answer
Answer with volume and recency: how many hours a week you currently spend in a lab, which materials and which procedures, and which technique you have rebuilt since dental school. This is the question that walks into the simulation lab with you, so vague reassurance about 'good hands' lands badly.
Ethical & scenario
4 questionsDescribe an ethical dilemma you have faced and how you handled it.
How to answer
Choose a genuine dilemma with competing goods — a patient refusing a referral, a billing error, a colleague cutting corners — then walk through how you identified the obligation, who you consulted, and what you documented. UW trains you for US licensure, so the winning pattern is escalation, not improvisation.
How would you define professionalism?
How to answer
Define it through behaviour, not adjectives: showing up prepared, keeping promises about time and cost, documenting honestly, and treating patients and staff with equal respect. Attach one short example from your practice. The trap is a dictionary answer that never touches what you personally do differently.
How would you go about serving an underserved community?
How to answer
Be concrete about access: prevention in schools, sliding-scale scheduling, working in community clinics and tribal or rural outreach, and the language skills you bring. Washington State has large rural and migrant populations, so tie the answer to a setting you can actually describe rather than a general wish to help.
What would you change about the lack of access to dental care if you were in charge?
How to answer
Show you understand the system, not just the problem: workforce distribution, Medicaid reimbursement, mid-level providers, school-based sealant programs, and the cost of emergency care. Then say which single lever you would pull and why. An answer with no mechanism behind it reads as a slogan.
Bench-day & skills-session prompts
4 questionsWalk me through the last restorative preparation you completed in a lab, step by step.
How to answer
Sequence it out loud — isolation, outline form, depth and taper, margin or finish line, evaluation and clean-up — in the vocabulary UW uses in its own courses. Because your bench work is graded blindly, the committee can only hear your process in the interview: precision in language is treated as a proxy for precision in the hand.
How do you work when you cannot see how your work is being judged?
How to answer
Name the discipline: verify your own reductions with measurements rather than the eye, photograph or re-inspect your work, and practise to a standard rather than to a time. UW grades the skills assessment blindly as it grades its own students, so the honest answer describes internal checkpoints rather than waiting for feedback.
Talk me through a fixed prosthodontic case you carried end to end.
How to answer
Follow the arc: assessment and records, preparation, impression or digital scan, provisionalisation, lab communication, delivery, and follow-up. Name one thing that went wrong and how you recovered. Fixed prosthodontics is an explicit part of UW's bench assessment, so hand-waving the lab stage is the trap.
How would you justify a treatment plan you are defending in writing and in front of a faculty grader?
How to answer
Structure it as diagnosis, options, evidence, risks and patient preference, and say what you would do if the patient declined the ideal plan. UW includes a written case-based exam in the same session, so the answer should show you can reason on paper as well as perform on a model.

Washington dental advanced standing interview — frequently asked questions
What is the Washington dental advanced standing interview format?
Invited finalists attend a three-day skills and interview session at the University of Washington School of Dentistry in Seattle. It combines an orientation to the dental school, interviews with selected faculty, and dental skills psychomotor assessments, including a written case-based exam. Interviews are held between June and July 2026 and the bench examination window falls in July and August 2026.
Does UW require a bench test for advanced standing applicants?
Yes. UWIDDS candidates must perform restorative, endodontic and fixed prosthodontic procedures on manikin and plastic teeth, plus a written case-based exam. All hand instruments, handpieces, plastic teeth and study models are provided, the requirements are communicated beforehand, and the result is graded blindly as in UW's regular courses and counts toward admission.
How long is the UW IDDS interview, and who conducts it?
UW does not publish the interview length, panel size or whether the file is open or closed, so confirm the specifics in your invitation. In practice the session interviews candidates with selected faculty and reads as open file, and candidates describe two one-on-one conversations of roughly 35 minutes each, held either virtually or on campus.
What TOEFL score does the UWIDDS require?
TOEFL iBT only. For exams taken before January 21, 2026, a score of 100 or higher is strongly recommended; for exams taken on or after that date, 5.00 or higher. There are no waivers — US citizens who graduated abroad must also take it — and the Home Edition, MyBest scores, and tests older than two years are not accepted. Submit the report directly to ADEA CAAPID.
Do I need the INBDE to apply to the UWIDDS?
Yes. You must pass the INBDE, or NBDE Parts I and II, and official score reports must be submitted through ADEA CAAPID. You may submit the application before your result is uploaded, but UW will not forward it to the Admissions Committee until the scores appear, and results more than five years old are still accepted.
How many letters of evaluation does UW require?
Three, submitted only through the CAAPID portal. They must be in English, on the recommender's letterhead, signed, and written within 12 months of your application. UW asks that they address your strongest and weakest characteristics and indicate class ranking where possible, with at least one letter from a dental professional who has worked with you in the last 12 months.
How large is the UW IDDS class?
The ADEA CAAPID listing shows a program size of 20 seats, flagged as an estimate, and UWIDDS states that only a small number of students are accepted each year. The cohort enters the predoctoral clerkship model full time for 10 quarters, so confirm the current intake and clinical rotation structure with the IDDS program office.
What are the UWIDDS deadline and start date?
The CAAPID application opens March 5, 2026 and closes June 1, 2026, and UW encourages you to apply as early as possible. File reviews begin in April, interview invitations are issued between May and June, and admitted students begin classes in January 2027 after a mandatory orientation in December 2026.
When do UW IDDS finalists hear back, and what does an offer require?
Admission status notifications are sent in August 2026. Accepted applicants respond to the offer letter with a non-refundable $5,000 deposit that is not applied toward tuition, satisfy UW's credentialing conditions, and — if they will study on a visa — submit a proof-of-financial-ability form to International Student Services before matriculation.
