  • NBEO does not allow candidates to transfer registration to a different administration. If you wish to withdraw from an exam, follow the guidelines for withdrawal listed on the website. When you are ready to take the exam, you must re-register.

  • You must be sponsored to take Part I ABS, Part II PAM, Part III CSE, TMOD, and ISE. Click here for more information.

  • If you wish to apply online but do not have a U.S. SSN, you will need to call our office to request an NBEO ID number. You will use this assigned number when applying, and for all subsequent applications. Please notify NBEO if you later receive a U.S. SSN.

  • No, you do not need to register for each exam separately. TMOD is embedded in Part II PAM, so you are taking both exams at the same time. You will have separate scores (one for Part II PAM and one for TMOD).


  • You may take the exams in any order you would like, if you meet eligibility requirements for the exam that you are registering for. In other words, you may take Part II PAM before Part I ABS as long as you are eligible to take Part II PAM. Please see the Exam Eligibility Policy here

  • Each state has its own requirements. Please contact your state board for licensure requirements.

  • A targeted administration is the first opportunity that students have to take the exam once they become eligible. A non-targeted administration is just another opportunity for students to take the exam.

STUDENTS: Please be reminded that upon verification of graduation and passage of all required NBEO Parts for the selected states, NBEO will send a free cumulative score report to the state boards you selected during your final examination (5 maximum). If you would like an official score report sent to you, you will need to order a score report online and select “self.”

NON-STUDENTS: Score reports for any state board can be quickly and easily ordered online and your request will be processed within 7 business days. You can also order a copy for yourself.

Unless requested by a candidate or state board, scores are submitted to state boards only (1) after a candidate passes all NBEO Parts required by the selected state boards, and (2) after NBEO receives notice of graduation verification from the candidate’s optometry school/college.

NBEO exam scores do not expire. After they are released, the scores are always available to the state board(s) you selected to have them released. State boards may have additional requirements for keeping scores active. Please check with the state in which you are seeking licensure as to their regulations.

NBEO automatically transmits the necessary score information to the Optometry Residency Match (ORMatch) through the ORMatch residency application process.

You will need to request a score report online. An official score report will be sent to you for distribution to ABCMO within 7 business days.

NBEO releases scores based upon a candidate’s authorization to release to an academic institution.


If you fail TMOD and pass Part II PAM, you will need to re-take the TMOD portion if your state requires TMOD for licensure. TMOD is offered as a stand-alone exam. Candidates who desire a TMOD-only score must select TMOD during registration.

If you fail the PAM portion of Part II PAM and pass the TMOD portion of Part II PAM, you will be taking both exams again when you re-take the Part II PAM exam because TMOD is embedded in the Part II PAM exam. The PAM portion of Part II PAM is not offered as a stand-alone exam.
