- CHI means Certified Heritage Interpreter, awarded through the National Association for Interpretation (NAI) via a peer-review process, not a seat-based test.
- The route has a 50-question multiple-choice literature review, four of six essays, two media examples and a 20-30-minute presentation video.
- The application costs USD 200 and is paid before you receive the application packet with detailed instructions.
- Eligibility sources conflict: four years/8000 hours is "recommended" on one page but "required" on a linked form. Get NAI's decision in writing.
What You Are Actually Preparing For
The Certified Heritage Interpreter credential is offered by the National Association for Interpretation (NAI). Candidates often assume it works like a typical certification exam: book a seat, sit for a fixed block of time, receive a score. The CHI route does not fit that mold. It is a professional peer-review and application process in which your knowledge and your demonstrated craft are both evaluated. If you are still orienting yourself, start with What Is CHI? and What Does CHI Stand For? to confirm you are looking at the heritage interpretation credential and nothing else that shares the acronym.
The current public route has four deliverables:
- A 50-question multiple-choice literature review
- Four of six essays, each no more than 500 words
- Two examples of self-created, non-personal interpretive media
- A 20-30-minute thematic presentation video
That mix changes how you should study. A candidate who spends every evening on flashcards but never drafts an essay or storyboards a media piece is preparing for roughly one fifth of the work. The best first-attempt strategy is to treat the literature review as one component and to build the written and visual work in parallel from the beginning.
Eligibility, Application and Fee Mechanics
The experience conflict you need to resolve early
Public NAI materials do not agree with each other, and a careful candidate should notice that before paying anything:
| Source | What it says about experience |
|---|---|
| Current NAI CHI webpage | Four years / 8000 hours is recommended; accepts an experience or academic resume |
| Linked eligibility form (undated) | Describes 8000 hours as required |
We do not know which wording governs your application, so do not guess. Contact NAI, ask which standard applies to you today, and keep the answer in writing. Our CHI requirements guide walks through the eligibility landscape in more detail. What is not established by the public record: a mandatory degree, a required prior CIG credential, or a mandatory in-person training-hour total. Do not assume any of those apply, and do not assume they do not; confirm with NAI.
Documentation
Experience verification applies, and self-employed interpreters are expected to supply self-employment documentation. If you work as a freelance exhibit writer, contract guide or independent program developer, begin gathering client letters, contracts, program flyers and project records now. Documentation is the kind of task that quietly eats weeks.
Fees and timing
- The application fee is USD 200, paid before the packet is delivered.
- No separate member and non-member application fee is published.
- The detailed instructions live in a private packet supplied after payment.
- The program record lists a one-year completion window. That figure is a completion deadline, not a seat-time limit for the literature review.
For the broader financial picture, including renewal and late-reinstatement costs, see the CHI certification cost breakdown. Because the current public route is undated and the legacy handbook link redirects to the NAI homepage, treat the packet you receive as the authoritative instruction set for formatting and submission.
The Seven Skill Areas, Domain by Domain
NAI publishes advanced knowledge, skills and abilities (KSAs) for the Certified Heritage Interpreter. We organize them into seven preparation categories. These are unweighted competency areas, not an official weighted blueprint, and they do not prove how the literature review is distributed. We do not know which area is largest, so avoid over-investing in any single one on the basis of rumor. Our companion piece, CHI Exam Domains: Complete Guide to All 7 Content Areas, goes deeper on each.
Domain 1: The history of the interpretive profession
Know how heritage interpretation developed as a field and who shaped its thinking.
- Be able to place major figures and ideas in sequence and explain why they mattered
- Connect historical developments to how interpreters work today
- Expect to use this knowledge as background context in your essays, not only on the literature review
Domain 2: The principles of interpretation
This is the intellectual core of the credential. Interpretation is distinguished from information delivery by its aims: provoking, relating and revealing meaning.
- Distinguish interpretation from simply presenting facts
- Explain how audience connection and meaning-making drive program design
- Be ready to apply principles to scenarios, not just define them
Domain 3: Current literature in the interpretive field
The public KSA list does not establish a complete reading list, so you cannot rely on a fixed bibliography.
- Read widely across foundational and contemporary interpretive writing
- Keep notes on each source: its central argument and how you would apply it
- Ask NAI whether the application packet identifies recommended reading
Domain 4: Developing and delivering thematic interpretive programs
This domain maps directly onto your presentation video. A thematic program is built around a central message, not a list of topics.
- Practice stating a theme as a full, meaningful sentence
- Structure a program so every part supports the theme
- Rehearse delivery to the 20-30-minute length
Domain 5: Writing measurable objectives
Objectives turn good intentions into something a reviewer can evaluate.
- Write objectives that describe what an audience will learn, feel or do
- Check each objective for observability and specificity
- Align objectives to your theme and program elements
Domain 6: Developing and designing engaging interpretive media
You must submit two examples of self-created, non-personal interpretive media, so this domain is both knowledge and production.
- Understand what makes media interpretive rather than purely informational
- Choose pieces you actually created and can discuss with confidence
- Note the "non-personal" requirement: these are media examples, not live programs
Domain 7: Interpretive writing
Your four essays, capped at 500 words each, are the most visible test of this domain.
- Practice saying something substantial in a tight word limit
- Write with clarity, a clear voice and a point of view
- Edit ruthlessly; going over the limit is an avoidable mistake
Conquering the 50-Question Literature Review
The literature review consists of 50 multiple-choice questions. Several things are not publicly verified: the split between scored and unscored items, the time allowed, the passing threshold, component minima and component weights. Our CHI passing score article covers what is and is not known. Because the timer is unverified, do not build your plan around an assumed duration. Ask NAI, and read the packet carefully once it arrives.
Also unverified: current open-book rules, calculator rules, proctoring requirements and resubmission rules. Those details matter for how you prepare, so confirm them rather than relying on forum posts of unknown age.
What the questions are likely to reward
Without claiming access to live questions, the competency list tells us what a literature review for this credential can reasonably probe: the historical development of the field, the principles of interpretation, familiarity with current writing, and applied reasoning about programs, objectives, media and writing. That suggests:
- Concept discrimination. Many wrong answers will be plausible. Practice explaining why an option is better, not just recognizing it.
- Application over recitation. Expect scenario-style thinking in which you apply a principle to a program or media decision.
- Breadth. With no published weights, uneven preparation is a risk. A balanced pass through all seven areas beats deep expertise in two.
You can use the practice questions on our main site to test recall and reasoning across these areas. Keep in mind that allocation of practice questions across domains is editorial, and domain counts in any bank do not establish official exam weights.
Key Takeaway
Because passing thresholds and weights are unverified, aim for consistent competence across all seven areas rather than gaming a presumed heavy domain. Check how difficulty is characterized in How Hard Is the CHI Exam? and what is known about outcomes in CHI Pass Rate: What the Data Shows. The pass rate is not publicly disclosed, so treat any number you see with suspicion.
Essays, Media Examples and the Presentation Video
The essays: four of six, 500 words maximum
You select four from a set of six. The exact prompts come with the application packet, so we will not speculate on their wording. What you can do beforehand is build the underlying skill:
- Write short practice pieces on interpretation principles and apply each to a real site or program you know well
- Practice cutting a 700-word draft to 500 without losing the argument
- Collect two or three personal examples from your own work that you can adapt to different prompts
Having a bank of real examples matters because strong essays in a field like this are grounded in practice. Generic claims about "engaging visitors" are weak; a specific program you ran, what you intended and what happened is stronger.
The media examples: two, self-created, non-personal
Choose media you built yourself. Good candidates might include a wayside panel, brochure, exhibit text, audio piece or similar interpretive product. Be ready to show how the piece connects to a theme and to an audience. Resist submitting something simply because it looks polished; the stronger choice is the piece that best demonstrates interpretive thinking.
The presentation video: 20-30 minutes, thematic
This is likely to be the most time-consuming deliverable. Plan for multiple takes. Practical sequence:
- Write your theme as a complete sentence before anything else.
- Draft measurable objectives (Domain 5) for the program.
- Outline the program so each section advances the theme.
- Rehearse to land comfortably within 20-30 minutes.
- Record, review, and fix audio and framing problems before you finalize.

Sequencing Your Preparation Around CHI Content
You need only one structured plan. Rather than a generic calendar, organize by what each domain feeds. The foundation areas (history, principles, literature) support everything else, while the production areas (programs, objectives, media, writing) take the longest, so start them early. The weeks below are a sample; compress or stretch them to fit your one-year window and your actual workload.
Settle logistics and read the foundations
- Resolve the eligibility question with NAI and start gathering experience documentation
- Begin Domain 1 (history) and Domain 2 (principles) reading
- Choose your presentation theme candidates
Build literature depth
- Work through Domain 3 (current literature), taking application notes on each source
- Start short essay drafts tied to Domains 1-3
- Take a first diagnostic set of practice questions to find weak areas
Programs and objectives
- Develop your thematic program (Domain 4) and write measurable objectives (Domain 5)
- Draft the presentation outline and begin rehearsing
Media and writing
- Select and refine your two media examples (Domain 6)
- Finalize essays under the 500-word cap (Domain 7)
Integration and review
- Record and polish the presentation video
- Run mixed practice sets across all seven areas and review missed items
- Re-read the packet instructions line by line before submitting
If you want a condensed reference to keep nearby while you work, the CHI cheat sheet collects the must-know facts in one place.
What Is Not Publicly Verified
Good preparation includes knowing the limits of public information. Several details commonly asked about remain unverified in the sources reviewed, and any site claiming certainty about them deserves skepticism.
| Topic | Status |
|---|---|
| Numerical passing threshold, component minima, component weights | Unverified |
| Timed literature-review duration | Unverified |
| Scored vs. unscored question split | Undisclosed |
| Pass rate | Not publicly disclosed |
| Open-book, calculator, proctoring and resubmission rules | Unverified |
| Which skill area is largest | Unknown; the seven areas are unweighted |
| CHI-specific salary premium | No verified premium |
| Testing-center provider | None verified; this is a peer-review process |
That last point about earnings is worth sitting with before you invest a year in the process. We have not verified a salary uplift tied specifically to the credential, so weigh the decision on professional recognition, career goals and employer expectations. Our CHI salary guide and analysis of whether the CHI is worth it lay out that reasoning honestly rather than promising a return.
After You Pass: Validity and Recertification
Once earned, the credential is valid for four years. Planning for recertification at the start saves headaches later, because continuing education should accumulate across those four years rather than in a last-minute scramble.
| Situation | Requirement |
|---|---|
| Standard renewal | 40 continuing-education hours and USD 100 |
| Late reinstatement (six months to two years late) | USD 300 and 60 continuing-education hours |
| More than two years late | Reapplication and review |
Keep a running log of workshops, conference sessions, courses and other qualifying activity with dates and hours. If you are still deciding whether to pursue certification at all, the overview pages What Is CHI Certification? and CHI Training are useful companions.
Frequently Asked Questions
No. The current public route is a professional peer-review and application process. It includes a 50-question multiple-choice literature review, four of six essays, two self-created media examples and a 20-30-minute thematic presentation video. No external testing-center provider has been verified.
The application fee is USD 200, paid before the packet is delivered. No separate member and non-member application fee is published. Renewal and late fees are covered in the recertification section above and in our cost breakdown.
Public sources conflict. The current NAI webpage describes four years or 8000 hours as recommended and accepts an experience or academic resume, while a linked undated form describes 8000 hours as required. Ask NAI which standard applies to you and get the answer in writing.
Numerical passing thresholds, component minima and weights are not verified in the public sources reviewed, and the pass rate is not publicly disclosed. Prepare for competence across all seven skill areas and the written, media and presentation components rather than chasing a rumored number.
No. Practice questions support knowledge preparation for the literature review, but the essays, media examples and presentation video must be created by you. Use a question bank such as our main practice test alongside real writing, design and presentation work.
Success on this route comes from treating it as a body of professional work rather than a memorization sprint. Resolve the eligibility question early, study all seven skill areas evenly, begin the essays and media well before the deadline, and use this study guide alongside the official packet as your checklist.
