What the Certified Postsecondary Instructor Credential Is
"CPI" stands for several unrelated credentials in different industries. On this site it means one thing only: the Certified Postsecondary Instructor credential, awarded and administered by the National Center for Competency Testing (NCCT). If a requirements list you find elsewhere mentions a different certifying body, different fees, or a different field entirely, it describes a different credential and does not apply here.
The credential is aimed at people who teach at the postsecondary level and want an independent, third-party validation of their instructional competence. That is a meaningful distinction: the credential does not certify that you know your subject. It certifies that you know how to teach it. Your subject expertise is established separately, through documentation, and the exam focuses on instructional practice. If you are still sorting out the basics, our explainers on what CPI certification is and what CPI stands for cover the naming and scope in more depth.
The Three Eligibility Requirements
NCCT sets three eligibility conditions for the Certified Postsecondary Instructor credential. You must satisfy all three before you can sit for the exam.
| Requirement | What NCCT Asks For | Practical Note |
|---|---|---|
| Teaching experience | Six months of full-time postsecondary teaching, or the equivalent | "Equivalent" is where part-time and adjunct work gets evaluated, so document your hours and courses carefully |
| Education | A U.S. high-school diploma or GED, or a college degree | A degree satisfies this; so does a diploma or GED |
| Supervisor reference | A reference verifying teaching experience, subject expertise, and good moral character | Submitted on the official CPI/Preceptor Reference Form |
Teaching experience: six months, full-time or equivalent
The experience requirement is modest in length but specific in kind. It must be postsecondary teaching, meaning instruction beyond the high-school level, such as in colleges, technical and vocational schools, or comparable programs. If your work has been part-time, adjunct, or spread across several institutions, the "or equivalent" language is what you will rely on. Before you apply, add up your actual instructional time and be ready to show how it adds up to the equivalent of six full-time months.
Education: diploma, GED, or degree
The educational floor is low. A U.S. high-school diploma or GED is enough, and a college degree also satisfies the requirement. This reflects the credential's focus: postsecondary instruction includes many trades, technical, and career-oriented programs where practitioners teach from deep field experience rather than from an academic pathway.
The Supervisor Reference: The Piece Candidates Underestimate
The most common source of delay is not the exam. It is the supervisor reference. NCCT requires a reference that verifies three separate things: your teaching experience, your subject expertise, and your good moral character. This is submitted using the official Certified Postsecondary Instructor (CPI)/Preceptor Reference Form (TE-0212RF, 2024 edition).
This is also where the credential's structure becomes clear. The exam content outline lists five general competencies. The first, primary-subject expertise, is not tested on the exam. It is verified through documentation, and the supervisor's attestation on the reference form is a central part of that documentation. The other four competencies become the tested domains.
Choosing the right person
- Pick someone who has observed your teaching or oversees your instructional work, such as a department chair, program director, or lead instructor.
- Make sure they can speak to all three items on the form, not just one. A reference who can only confirm your hours but not your subject mastery leaves the form incomplete.
- Give them lead time. Supervisors are busy, and a form that sits in an inbox can stall your whole timeline.
- Brief them in advance on what the form asks so they are not seeing the questions for the first time.
Key Takeaway
Request the reference form early, before you begin heavy exam prep. Your study schedule is within your control; your supervisor's response time is not. Starting the paperwork first protects you from a long wait after you are already test-ready.
What Eligibility Leads To: The Exam Itself
Understanding the exam helps you decide whether you are ready to apply. Per NCCT's Candidate Handbook (revised January 2026), the exam is a computer-based, English-language test with 200 scored questions, zero pretest questions, and a four-hour time limit. Every item counts toward your result. Because there are no unscored trial questions mixed in, you cannot assume any item is "just a pretest" and relax on it.
Questions are four-option multiple choice, and the handbook also describes innovative item types: multiple select, hotspot, and drag and drop. Note that the older Rev. 2024 content outline describes multiple-choice questions only. The newer handbook controls the format description, so prepare for the broader range of item styles.
The four tested domains and their item counts
Domain 1: Demonstrate knowledge of principles of instruction at the postsecondary level
The foundations of how adults learn and how instruction works in postsecondary settings. 45 questions.
Domain 2: Design and plan instruction to meet learning objectives
Translating objectives into lesson and course design. 45 questions.
Domain 3: Create and maintain a functional learning environment
The largest allocation on the exam, at 56 questions. This covers the practical conditions that make learning possible in your classroom, lab, or shop.
Domain 4: Assess all aspects of learning to improve quality
Measuring learning and using results to improve instruction. 54 questions.
These are official item counts from the content outline, not percentage weights published by the issuer. Domain 3 is the biggest single block, followed closely by Domain 4. For a full breakdown of what each area covers, see our complete guide to the four CPI exam domains.
Fees and Registration Mechanics
| Item | Amount |
|---|---|
| Exam fee | USD 119 |
| Remote testing add-on | USD 44 |
| Site sitting fee | May apply at individual NCCT-authorized testing sites |
| Optional official CPI Interactive Review System | USD 69.95 |
The base exam fee is USD 119. If you test remotely, add USD 44. If you test in person at an NCCT-authorized site, that individual site may charge its own sitting fee, so ask before you book. The CPI Interactive Review System is NCCT's optional official study product and is not required for eligibility or registration. For a fuller picture of what you will spend from application through renewal, see our CPI certification cost breakdown.
Plan your registration in this order: confirm you meet the three eligibility requirements, send the reference form to your supervisor, then schedule your exam once your documentation is moving. Timing and scheduling details are covered in our guide to CPI exam dates and scheduling.
Testing Rules and Remote Setup
Testing is proctored and closed book. You must present valid identification that matches your registration. For remote CPI testing, NCCT's support FAQ prohibits books, notes, and calculators. Guessing is not penalized, so you should answer every question rather than leaving blanks.
If you choose remote delivery, live proctoring is provided through ExamRoom.AI, and NCCT's Guide to Remote Testing sets the equipment requirements:
- A computer with a working webcam
- A working microphone
- A secondary phone or tablet camera for the additional view the proctor requires
Check your equipment well before test day and read the remote testing guide in full. A missing secondary camera is an avoidable reason to lose an appointment you paid for.
Retake Waiting Periods
Eligibility is not a one-time gate you clear once; the retake policy is part of the requirements picture. The handbook sets escalating waiting periods:
| After | Minimum Wait |
|---|---|
| First failure | At least 30 days |
| Second failure | At least 30 days |
| Third failure | 90 days |
| Fourth and each later failure | 180 days |
Fifth and later attempts also require an appeal to the Director of Testing and evidence of remediation. The practical lesson: treat your first attempt seriously. Each failure lengthens the delay, and the fee applies again. If you want a realistic sense of how demanding the test is before you commit, read how hard the CPI exam is.
Keeping the Credential Active
Qualifying is only half of the story. Per NCCT's Guide to Recertification (2026 Revision), you keep your status active annually by:
- Completing 12 continuing-education contact hours
- Paying USD 89 for a single certification
- Adhering to NCCT's ethics requirements
This is an annual maintenance cycle, not a five-year active term. Five consecutive years without renewal invalidates the credential. If you are weighing the long-term commitment, our analysis of whether the CPI certification is worth it frames the ongoing cost against the benefit.
Planning Prep Around the Four Domains
Because the exam allocates its 200 questions unevenly, your prep time should not be split evenly either. Here is one way to sequence preparation once your eligibility paperwork is underway:
Domain 1 and Domain 2 foundations
- Cover principles of postsecondary instruction (45 questions)
- Practice writing and aligning learning objectives, since Domain 2 (45 questions) builds directly on this
Domain 3: the largest block
- Dedicate the most time here, as it carries 56 questions
- Work through learning-environment scenarios from your own classroom, lab, or shop
Domain 4 and mixed review
- Study assessment of learning (54 questions)
- Practice multiple select, hotspot, and drag-and-drop formats under timed conditions
For a deeper study framework, see our CPI study guide, and for a quick-reference summary use the CPI cheat sheet. When you are ready to test your knowledge against realistic questions, take a CPI practice test to find your weak domains before the real exam.
Frequently Asked Questions
No. NCCT accepts a U.S. high-school diploma or GED or a college degree. You must still have six months of full-time postsecondary teaching (or the equivalent) and a supervisor reference.
No. Primary-subject expertise is verified through documentation, including the supervisor reference. The exam's four domains test teaching practice: instruction principles, planning, learning environment, and assessment.
The requirement is six months of full-time postsecondary teaching or the equivalent. Part-time work may qualify as equivalent experience, so document your hours and courses and confirm details with NCCT.
The reference must verify your teaching experience, your subject expertise, and your good moral character, using NCCT's official CPI/Preceptor Reference Form.
The exam fee is USD 119. Remote testing adds USD 44, and individual testing sites may charge a sitting fee. Annual renewal is USD 89 for a single certification, plus 12 continuing-education hours.
Meeting the requirements is a matter of paperwork and preparation rather than a high bar of credentials. Confirm your teaching experience, line up your supervisor early, and prepare by domain with the heaviest emphasis on creating and maintaining a functional learning environment.
