If you typed "CHS-JS1 pass rate" into a search engine hoping for a tidy percentage, you probably noticed something unsettling: there is no authoritative number. That absence is itself the most important data point. This article explains exactly what is and is not known about outcomes on the CodeHS JavaScript Level 1 Certification, why the figure you want does not exist in public sources, and how to use the information that is available to make your own attempt count.
For the broader landscape, our companion piece on the CHS-JS1 pass rate covers the same question from a summary angle, while this article goes deeper into what the verified exam mechanics imply for your odds.
What the Data Actually Shows
Let's separate what is documented from what is rumor. The CodeHS JavaScript Level 1 Certification is an online, 90-minute exam with 45 multiple-choice questions and a passing score of 60%. Those figures come directly from CodeHS documentation. What CodeHS does not publish, as far as any verifiable source shows, includes:
- A cohort pass rate (the share of test-takers who clear 60%)
- An average or median score
- A split between scored and unscored questions
- Percentage weights for each exam topic group
If you are new to the credential itself, what CHS-JS1 is and what CHS-JS1 stands for clear up the naming before you go hunting for statistics.
The 60% Cut Score Is Not a Pass Rate
This is the single most common confusion. A passing score tells you how much of the exam you must answer correctly. A pass rate tells you what fraction of all candidates actually succeed. They answer different questions, and only the first is published.
| Concept | What It Measures | Published for CHS-JS1? |
|---|---|---|
| Passing score | Minimum percentage of the exam you must earn | Yes, 60% |
| Pass rate | Share of candidates who meet that minimum | No verified figure |
| Score distribution | How scores cluster across all candidates | No verified figure |
| Topic-level report | Your own performance by topic group | Yes, given to each candidate |
Do the arithmetic that actually helps you: 60% of 45 questions works out to 27 correct answers. Aim for a comfortable cushion above that, because you cannot know which questions are harder or how the platform scores partial exposure to any topic. For a full breakdown of how the threshold works, see CHS-JS1 passing score: exactly what you need to pass.
Exam Format and What It Means for Outcomes
Format shapes results more than most candidates realize. Here is the verified structure:
- 45 multiple-choice questions, randomly selected
- 90 minutes, completed in a single sitting
- A JavaScript examination reference sheet is provided during the exam
- CodeHS suggests having paper, a pencil, and a calculator nearby
- Running code in another website or program is prohibited
Ninety minutes for 45 questions gives you two minutes per question on average. That is generous for recall items but tighter for questions that require tracing a loop or predicting the output of nested conditionals by hand. Because you cannot run code elsewhere, tracing code on paper is the core skill the format rewards. Candidates who only learned JavaScript by running programs and checking the console often discover that predicting output mentally is a different muscle.
To gauge where this lands on the difficulty scale, read how hard the CHS-JS1 exam is.
The Six Domains Behind Your Score Report
CodeHS lists six top-level topic groups for the exam. Importantly, these are official topic headings, not a percentage-weighted blueprint and not a count of course modules. Since no weights are published, assume each area deserves serious attention. Your results include a topic-level performance report, so a weak area will be visible, but only after you have already spent a voucher.
Domain 1: Data Types and Operators
The foundation of everything else. Expect questions that test whether you can predict what an expression evaluates to.
- Numbers, strings, and booleans, and how they behave
- Arithmetic, comparison, and logical operators
- Order of operations and type-related surprises
Domain 2: Conditionals
Decision-making logic, where small mistakes in boolean reasoning cost points.
- if, else if, and else chains
- Combining conditions with logical operators
- Tracing which branch executes for a given input
Domain 3: Loops
Repetition and the mental tracing that goes with it.
- for and while loops and their termination conditions
- Counting iterations and predicting final values
- Off-by-one errors and infinite-loop recognition
Domain 4: Program Structure
How code is organized and how pieces of a program interact.
- Functions, parameters, and return values
- Variable scope and how data flows between functions
- Reading a multi-function program and predicting its result
Domain 5: Error Handling
Recognizing and reasoning about code that does not behave as intended.
- Identifying the source of a bug from a snippet
- Understanding what kinds of errors a program can raise
- Reasoning about how a program responds when something goes wrong
Domain 6: Objects
Working with structured data using key-value properties.
- Creating objects and accessing or modifying properties
- Iterating over and reasoning about object contents
- Combining objects with functions and loops
A full walkthrough of each group lives in the CHS-JS1 exam domains guide. Note that practice courses and certification practice listings help you prepare but do not establish exhaustive coverage or official weights, so use them as training, not as a definition of what is tested.
Retakes, Vouchers, and the Cost of a Second Attempt
Here is where the missing pass rate matters financially. Each purchased voucher permits one attempt. There is no numerical cap on retakes, but every additional attempt requires another voucher. CodeHS provides school and district voucher pricing by direct quote, and no public numeric fee was verified, so we will not guess at a price. Our CHS-JS1 certification cost breakdown explains how the quote-based model works.
| Voucher Fact | What It Means for You |
|---|---|
| One attempt per voucher | A failed attempt cannot be "re-sat" for free |
| No numeric retake limit | You can try again, but only by obtaining another voucher |
| Unused vouchers expire at contract end | School/district vouchers do not roll over between school years |
| Quote-based pricing | Cost is negotiated through CodeHS, not posted publicly |
Key Takeaway
Because vouchers are tied to a contract term and do not roll over, a teacher or school should plan the testing window early. Scheduling a retake late in a contract year may collide with an expiring allotment. Check your timeline against the CHS-JS1 exam dates and scheduling guide.
Test-Day Conditions That Influence Results
Candidates can test at home or at school, with a teacher or authorized proctor monitoring through the CodeHS Certifications app and Proctor Dashboard. The exam runs under an Honor Code, uses randomly selected questions, and activates Focus Mode.
Be precise about what Focus Mode is. It blocks navigation to other CodeHS pages. It is not described as a system-wide browser lockdown, so do not assume the platform polices everything on your computer. That does not make other resources fair game: external websites, collaboration, copying or sharing exam questions, and running code elsewhere are all prohibited under the rules.
- Accommodations: extended-time and read-aloud are supported; other requests require platform review, so ask well before test day.
- Results: released within 36 hours on school days, with an overall score and a topic-level report.
- Certificate: successful candidates receive a downloadable certificate that expires after 10 years.
Eligibility is simple: there are no certification prerequisites. Introduction to Computer Science in JavaScript (Corgi) is recommended preparation, not a requirement. More detail is in CHS-JS1 requirements and eligibility.
A Domain-by-Domain Plan Built Around the Exam
Since outcome statistics are unavailable, the best predictor you control is coverage plus tracing practice. The schedule below sequences the six domains in dependency order: later topics reuse earlier ones, so skipping ahead creates avoidable confusion.
Data Types, Operators, and Conditionals
- Hand-evaluate expressions without running them
- Trace if/else chains with varied inputs on paper
- Practice with the reference sheet open
Loops and Program Structure
- Trace loops line by line, tracking every variable
- Predict return values across multi-function programs
- Hunt for off-by-one and scope mistakes
Error Handling, Objects, and Full Review
- Diagnose bugs from short snippets
- Combine objects with loops and functions
- Take timed full-length practice sets and review misses by domain
Because the topic-level report is the only feedback CodeHS gives, simulate it yourself: after each practice set, tally misses by domain and revisit the weakest group. Our CHS-JS1 practice tests are organized so you can do exactly that, and the CHS-JS1 study guide expands this approach. For a fast final review, use the CHS-JS1 cheat sheet the day before.
Who Takes This Exam and Why
The audience skews toward students in CodeHS-based courses, with teachers and districts managing vouchers and proctoring. A passing result gives a student a concrete, verifiable credential to show alongside coursework. Whether that credential moves the needle for hiring or college applications depends on context, and we avoid quoting earnings or placement numbers because none are verified. For an honest look, read whether the CHS-JS1 certification is worth it and CHS-JS1 jobs.
Frequently Asked Questions
No official pass rate has been verified for the CodeHS JavaScript Level 1 Certification. CodeHS publishes a 60% passing score, which is a cut score, not the share of candidates who pass. Be skeptical of any specific percentage without a CodeHS source.
The passing score is 60% on a 45-question exam, which corresponds to 27 correct answers. Because you cannot see which items are weighted or how they are scored, aim well above that threshold when practicing.
Yes. There is no numerical retake limit, but each attempt requires another purchased voucher. Unused school or district vouchers expire at the end of the contract term and do not roll over between school years.
Results are released within 36 hours on school days. You receive an overall score and a topic-level performance report, and successful candidates can download a certificate that is valid for 10 years.
No. There are no certification prerequisites. Introduction to Computer Science in JavaScript (Corgi) is recommended preparation, not an eligibility requirement, so any candidate approved by their school or district can sit the exam.
The honest takeaway from the data is that the numbers you want do not exist publicly, but the numbers that do exist, 45 questions, 90 minutes, 60% to pass, one attempt per voucher, are enough to plan a disciplined, domain-by-domain preparation. Build your tracing skills, use the reference sheet fluently, and treat your first voucher as the only one you intend to use.
