Who Can Sit for the CodeHS Web Development Level 1 Exam
If you are searching for the requirements to qualify for CHS-WDEV1, the short answer is refreshingly simple: there are no certification prerequisites. CodeHS does not ask you to hold another credential, finish a specific number of courses, or submit proof of prior experience before you are allowed to take the Web Development Level 1 Certification exam.
That said, "no prerequisites" is not the same as "no preparation needed." The exam is a 45-question, 90-minute test with a 60% passing score, and it covers real technical content: JavaScript embedded in HTML, jQuery, data handling, and website building and maintenance. This guide separates what CodeHS actually requires of you from what it merely recommends, so you do not waste time chasing hurdles that do not exist or skip preparation that does matter.
If you are new to the credential itself, start with What Is CHS-WDEV1 Certification? for the big picture, then return here for the qualification details.
The Requirements That Actually Exist
Because the credential has no formal admission gate, the real "requirements" are practical and logistical. Think of them as four things you need in place before test day:
- Access to a voucher. The exam is delivered through CodeHS, and attempts are tied to purchased vouchers, typically arranged by a school or district.
- A supervised testing setup. Testing happens at home or at school, monitored by a teacher or authorized proctor through the CodeHS Certifications app and Proctor Dashboard.
- A single uninterrupted block of time. The exam must be completed in one sitting within the 90-minute limit.
- Agreement to the Honor Code. You must follow the exam rules, which prohibit outside resources, collaboration, and sharing questions.
Recommended Preparation vs. Required Eligibility
CodeHS recommends that candidates complete a Web Development or Web Design and Development course before testing. The key word is recommended. It signals the path most students take and the one most likely to leave you ready, but it is not a checkbox the system verifies before you test.
| Item | Required? | What it means for you |
|---|---|---|
| Certification prerequisites | No | No prior credential or minimum score is needed to sit. |
| Web Development or Web Design and Development course | Recommended only | Strongly advisable preparation, but not an eligibility rule. |
| Prior HTML, CSS, or JavaScript knowledge | Not an admission requirement | Useful for passing; not checked before you test. |
| Purchased voucher | Yes, in practice | Each voucher permits one attempt. |
| Proctored, single-sitting session | Yes | Teacher or authorized proctor monitors via CodeHS tools. |
| Honor Code agreement | Yes | Governs what you may and may not do during the exam. |
Practically, the recommended course is how most candidates build the skills the exam measures. If you are self-directing instead, you can still qualify to test, but you take on the job of covering the same ground yourself. The CHS-WDEV1 Study Guide lays out how to do that systematically.
Vouchers: How Access to the Exam Works
CodeHS handles exam access through vouchers rather than an open public registration page. Understanding the voucher model prevents the most common planning mistakes.
What a voucher gives you
- One attempt per voucher. Each purchased voucher permits a single exam attempt.
- Unlimited retakes in principle. There is no numerical cap on retakes, but every additional attempt needs another purchased voucher.
- School and district purchasing. CodeHS provides school and district voucher pricing by direct quote. No public numeric fee was verified, so quoted figures from CodeHS or your school are the only reliable source.
The expiration trap
Unused school or district vouchers expire at the end of the contract term and do do not roll over between school years. If your teacher or district holds vouchers for your class, ask about the contract end date early. A voucher that goes unused when the term closes is simply gone, which can turn a "free" retake into a budget conversation.
Scheduling questions, including when your school offers testing sessions, are covered in CHS-WDEV1 Exam Dates: Testing Windows, Deadlines & Scheduling.
Exam-Day Rules You Must Meet
Qualifying to test also means agreeing to operate within CodeHS's proctoring framework. These are the conditions you accept when you start.
Format and environment
- 45 multiple-choice questions in a 90-minute online examination.
- Single sitting: you cannot pause and return later.
- Randomly selected questions: candidates do not all see an identical set.
- Focus Mode: blocks navigation to other CodeHS pages during the exam. It is not described as a system-wide browser lockdown, so the Honor Code and your proctor remain the primary safeguards against outside resources.
- At home or at school: either location can work, provided a teacher or authorized proctor monitors through the CodeHS Certifications app and Proctor Dashboard.
What you can and cannot use
This is where Web Development differs from some other CodeHS exams. No examination reference sheet is provided for Web Development. You will not get a syntax cheat sheet on screen, so jQuery selectors, event methods, and JavaScript-in-HTML patterns need to live in your memory.
- Allowed: CodeHS suggests paper, a pencil, and a calculator for working things out.
- Prohibited: external websites, collaboration with others, copying or sharing exam questions, and running code in another website or program.
That last rule matters for a coding exam. You cannot paste a snippet into a browser console or an online editor to see what it outputs. You need to trace code by reading it, which is a skill worth practicing before test day. If you want a compact memory aid for what you will have to recall unaided, the CHS-WDEV1 Cheat Sheet is a good study companion (just remember you cannot bring it into the exam).
Key Takeaway
Because there is no reference sheet and you cannot run code elsewhere, practice reading and tracing HTML, JavaScript, and jQuery by hand on paper. The skill the exam rewards is predicting what code does without executing it.
The Four Domains You Must Be Ready For
Meeting the logistical requirements gets you into the exam room. Meeting the content expectations gets you through it. The exam overview groups its topics under four headings. These are official topic groups, not a percentage-weighted blueprint, so do not assume any one domain counts more than another. For a fuller walkthrough, see CHS-WDEV1 Exam Domains: Complete Guide to All 4 Content Areas.
Domain 1: JavaScript in HTML
How JavaScript connects to and manipulates a web page, including the building blocks that make pages interactive.
- Embedding and linking scripts within HTML documents
- Working with the page structure from code
- Callbacks and synchronization, which the exam overview expressly retains
Domain 2: jQuery
The library-based approach to selecting elements, responding to events, and changing what users see.
- Selecting and modifying page elements with jQuery
- Handling user events
- Recognizing how jQuery statements read and what they produce
Domain 3: Storing and Collecting Data
How a web application gathers, holds, and works with information.
- Forms and the data users submit through them
- APIs and retrieving data from outside sources
- User-data analysis
Domain 4: How to Build and Maintain a Website
The practical, end-to-end side of putting a site into the world and keeping it running.
- Hosting a website
- Using a content management system (CMS)
- Ongoing maintenance considerations
One clarification worth making: the CodeHS preparation curriculum also covers topics such as JSON, cookies, and local storage. These appear in the course outline, but they are not separately listed exam objectives or additional domains, and the outline does not guarantee exhaustive exam coverage. Treat them as valuable preparation that supports Domain 3, not as a promise of what will appear.

Accommodations and Special Requests
Being eligible to test includes being able to test fairly. CodeHS supports extended-time and read-aloud accommodations directly. Other accommodation requests go through platform review, so they should be raised early rather than on exam day.
- Talk to your teacher or proctor well before your scheduled session.
- Confirm which accommodations are already attached to your account.
- For anything beyond extended time or read-aloud, allow extra lead time for review.
A Domain-Ordered Readiness Plan
Since the credential has no prerequisites, your preparation order is entirely your choice. Sequencing by dependency works best, because later domains lean on earlier ones. Here is one way to stage it:
JavaScript in HTML
- Review how scripts attach to a page and how code changes page content
- Practice callbacks and synchronization by tracing execution order on paper
jQuery
- Rebuild selector and event-handler patterns from memory
- Predict output of short jQuery snippets without running them
Storing and Collecting Data
- Work through forms, API calls, and user-data analysis scenarios
- Review JSON, cookies, and local storage as supporting preparation
Build and Maintain a Website, then full review
- Cover hosting and CMS use
- Take timed practice sets sized to the real 45-question, 90-minute format
Dependency is the reason for this order: you cannot reason about jQuery without understanding the JavaScript underneath, and data handling makes little sense until you can manipulate a page. When you are ready to test yourself under realistic conditions, try the CHS-WDEV1 practice tests and watch your timing against the 90-minute limit.
After the Exam: Results, Certificate, and Expiration
Part of understanding the requirements is knowing what the finish line looks like.
- Results timing: released within 36 hours on school days.
- What you receive: an overall score plus a topic-level performance report, which is useful if you need to retake.
- Certificate: successful candidates receive a downloadable certificate.
- Validity: earned certificates expire after 10 years.
The 60% passing score is the threshold for success on your attempt. It is not a cohort pass rate, and no official pass rate has been verified, so be cautious about any site quoting one. For what the threshold means in practice, read CHS-WDEV1 Passing Score: Exactly What You Need to Pass. And if you are weighing whether the effort is worthwhile, Is the CHS-WDEV1 Certification Worth It? examines the return on that investment.
Frequently Asked Questions
No. There are no certification prerequisites. CodeHS recommends a Web Development or Web Design and Development course as preparation, but that recommendation is not an eligibility requirement.
Prior knowledge is not an admission requirement for the certification. It will, however, strongly affect whether you pass, since the exam tests JavaScript in HTML, jQuery, data handling, and website building and maintenance.
There is no numerical limit on retakes, but each voucher permits only one attempt, so every additional attempt requires another purchased voucher. Unused school or district vouchers also expire at the end of the contract term.
Yes, testing is available at home or school with teacher or authorized proctor monitoring through the CodeHS Certifications app and Proctor Dashboard. No reference sheet is provided for Web Development; CodeHS suggests paper, a pencil, and a calculator.
Earned certificates expire after 10 years. Results, including an overall score and topic-level report, are released within 36 hours on school days, and successful candidates can download their certificate.
Qualifying for CodeHS Web Development Level 1 is straightforward on paper: secure a voucher, arrange proctored testing, and agree to the Honor Code. The real work is mastering the four domains without a reference sheet.
