What the CodeHS Web Development Level 1 Certification Actually Is
The Web Development Level 1 Certification is issued and administered by CodeHS, the same platform that delivers the Web Development course many students take in school. It is an online, proctored, multiple-choice examination that measures whether a student can work with the building blocks of an interactive, data-aware website. If you have seen the abbreviation CHS-WDEV1 and wondered about it, the short answer is covered in What Is CHS-WDEV1?; on this site, it refers specifically to this CodeHS credential and nothing else.
Two features distinguish it from many other entry-level web credentials. First, it is built around a classroom pipeline: schools and districts purchase vouchers, and teachers or authorized proctors supervise sessions through the CodeHS Certifications app. Second, its scope goes well beyond static markup. The official exam overview explicitly retains jQuery, callbacks and synchronization, APIs, forms, user-data analysis, hosting, and use of a content management system. That is a broader and more programming-heavy scope than a pure HTML-and-CSS design exam.
Exam Format: 45 Questions, 90 Minutes, 60% to Pass
The format is straightforward, which means your preparation can focus on content rather than logistics.
| Feature | Detail |
|---|---|
| Question count | 45 multiple-choice questions |
| Time limit | 90 minutes, completed in one sitting |
| Passing score | 60% |
| Delivery | Online, at home or at school, with teacher or authorized proctor monitoring |
| Question selection | Randomly selected questions |
| Reference sheet | None provided for Web Development |
| Prerequisites | None |
Ninety minutes for 45 questions works out to an average of two minutes per question. That is generous for recall questions but tighter for questions that ask you to trace a short jQuery snippet or predict the output of code involving callbacks. Practice reading code quickly and accurately rather than only writing it. For a deeper look at how the 60% line works in practice, see CHS-WDEV1 Passing Score 2026.
The Four Exam Topic Groups
The issuer's exam overview lists four top-level topic groups. They are official groupings of exam topics, not a percentage-weighted blueprint and not a count of course modules. Because no official weights are published, treat all four as fair game and avoid skipping any of them. For a longer treatment of each area, read CHS-WDEV1 Exam Domains 2026: Complete Guide to All 4 Content Areas.
Domain 1: JavaScript in HTML
This group covers how JavaScript lives inside and interacts with a web page. Expect questions that connect code to the document the user actually sees.
- Embedding scripts in an HTML page and understanding how the browser runs them
- Reading and changing page content and attributes from JavaScript
- Responding to user actions such as clicks and input
- Core language skills the page logic depends on: variables, functions, conditionals, loops, and arrays
Domain 2: jQuery
jQuery remains explicitly in scope, which surprises candidates who assume it is outdated. Because it is on the official overview, it is testable.
- Selecting elements with jQuery selectors and understanding how they differ from plain JavaScript lookups
- Handling events and modifying content, styles, and visibility
- Using jQuery's shorthand to make the page respond to users
- Recognizing how jQuery code maps to the equivalent plain JavaScript approach
Domain 3: Storing and Collecting Data
This is the broadest group and the one most likely to feel new to students who have only built static pages. It spans how a site gathers data, how it receives data, and how it makes sense of data.
- Forms: building them, collecting input, and handling submissions
- APIs: requesting data from external services and working with the responses
- Callbacks and synchronization: understanding why some code runs later than other code, and how to coordinate results
- User-data analysis: interpreting information collected from users
- Related preparation-curriculum topics such as JSON, cookies, and local storage appear in the CodeHS course outline, though they are not listed as separate exam objectives
Domain 4: How to Build and Maintain a Website
The final group moves from code to the lifecycle of a real site.
- Hosting: what it means to put a site on the web and make it reachable
- Using a content management system (CMS) to build and update a site
- Maintaining and updating a site after launch
- How the pieces from the other three groups fit together in a working website
Key Takeaway
Callbacks and synchronization sit inside Domain 3, not Domain 1, which is easy to overlook. If you only drill DOM manipulation and jQuery, the asynchronous-code questions will hurt you. Give timing and ordering of code execution its own dedicated study block.
Vouchers, Retakes, and Expiration
CodeHS prices certification through school and district vouchers, arranged by direct quote. No public numeric fee has been verified, so any specific dollar amount you see quoted elsewhere should be treated with caution. The practical details below matter more than a number, and the full breakdown lives in CHS-WDEV1 Certification Cost 2026.
- One voucher, one attempt. Each purchased voucher permits a single exam attempt.
- Retakes are not capped by number. There is no stated numerical limit on retakes, but every additional attempt requires another purchased voucher.
- Vouchers expire. Unused school or district vouchers expire at the end of the contract term and do not roll over between school years.
Because there is no prerequisite credential, eligibility is not the hurdle. Taking the Web Development or Web Design and Development course is the recommended preparation path, but it is not a condition of sitting the exam. The distinction is explained further in CHS-WDEV1 Requirements 2026.
Test Day: Proctoring, Focus Mode, and What You May Bring
How the session is supervised
You can test at home or at school. Either way, a teacher or authorized proctor monitors the session through the CodeHS Certifications app and the Proctor Dashboard. The exam must be completed in a single sitting, you agree to an Honor Code, and the questions are randomly selected from the pool.
Focus Mode, accurately described
The exam uses Focus Mode, which blocks navigation to other CodeHS pages. It is worth being precise here: it is not described as a system-wide browser lockdown. That does not mean you are free to look things up. The rules still prohibit external websites, collaboration, copying or sharing exam questions, and running code in another website or program. Treat the rules as a full closed-book environment regardless of what the software physically prevents.
What to have on your desk
No examination reference sheet is provided for Web Development. CodeHS suggests having paper, a pencil, and a calculator available. For a code-heavy exam, scratch paper is genuinely useful: sketch the order in which callbacks fire, write out a selector's target elements, or trace a loop by hand.
Accommodations
Extended-time and read-aloud accommodations are supported. Other accommodation requests require platform review, so raise them with your teacher well before test day rather than the morning of the exam.
Key Takeaway
Because no reference sheet exists, memorize the small set of syntax patterns that appear repeatedly: jQuery selector and event forms, the shape of a callback function, and the basic structure of a form and its submission. A one-page recall drill, like the one described in our CHS-WDEV1 Cheat Sheet, is a good way to test yourself.
Results, Certificate, and Validity
Results are released within 36 hours on school days. You receive an overall score along with a topic-level performance report, which is the most useful feedback if you need to retake. Look at which topic groups pulled your score down and aim your next round of study there.
Candidates who pass receive a downloadable certificate. Earned certificates expire after 10 years, which is a long validity window by technology-credential standards. Whether the credential is worth the effort for your situation is a separate question, which we examine in Is the CHS-WDEV1 Certification Worth It?
Matching Your Prep Weeks to the Four Domains
Since the four groups build on one another, the order in which you study them matters more than any general-purpose technique. Here is a sequence that follows the dependencies between topics. For a fuller plan, see the CHS-WDEV1 Study Guide 2026.
JavaScript in HTML
- Review how scripts attach to a page and how the browser executes them
- Practice reading short snippets that change page content after a click
- Re-learn functions, conditionals, loops, and arrays, since every later domain relies on them
jQuery
- Translate plain JavaScript examples into jQuery and back again
- Drill selectors and event handlers until you can read them at a glance
- Practice predicting what a short jQuery block does to a page
Storing and Collecting Data
- Work through forms, then APIs, then callbacks and synchronization, in that order
- Trace asynchronous code on paper to see the order operations complete
- Review JSON, cookies, and local storage from the course outline as supporting material
Building and Maintaining a Website, then full review
- Cover hosting and CMS concepts, which are mostly conceptual and quick to review
- Take timed practice sets of 45 questions in 90 minutes
- Revisit whichever domain your practice scores show as weakest
The reasoning is simple. Domain 1 gives you the language foundation, Domain 2 reuses it through a library, and Domain 3 adds the hardest new idea, asynchronous behavior. Domain 4 is the most conceptual, so it is best placed late when you can connect it to everything else. CodeHS also lists a matching Level 1 Certification Practice course in its public catalog; using it alongside the standard Web Development course gives you question-style familiarity. Keep in mind that practice courses are preparation tools and do not establish exhaustive exam coverage. For a sense of what to expect in terms of challenge, see How Hard Is the CHS-WDEV1 Exam?
You can also build timing habits with the practice questions on the main practice test site, using the same 45-question, 90-minute constraint you will face on exam day.
Who Benefits From This Credential
The audience for this certification is primarily students in school and district programs, particularly those in CodeHS Web Development or Web Design and Development courses. For them, the certificate is a verifiable record of applied skill that goes beyond a course grade. It can support a portfolio, a college application, or an early-career resume entry.
It is worth keeping expectations realistic. The credential demonstrates foundational competence with scripting, jQuery, data handling, and site deployment. It is an entry-level signal rather than a replacement for a portfolio of real projects. If you are weighing earnings or employer interest, read CHS-WDEV1 Salary Guide 2026 and CHS-WDEV1 Jobs; no verified salary figures are tied to this specific credential, so treat any precise number with suspicion. If you would like a broader orientation to the credential and its terminology, CHS-WDEV1 Certification and What Is CHS-WDEV1 Certification? cover the basics.
When you are ready to test your recall against realistic questions, head to the CHS-WDEV1 practice exam for timed sets that mirror the multiple-choice format.
Frequently Asked Questions
The exam contains 45 multiple-choice questions with a 90-minute time limit. It must be finished in a single sitting, and the passing score is 60%.
No. There are no certification prerequisites. The Web Development or Web Design and Development course is recommended preparation, but it is not an eligibility requirement for the exam.
No reference sheet is provided for Web Development, and external websites are prohibited. CodeHS suggests paper, a pencil, and a calculator for working through problems by hand.
There is no stated numerical limit on retakes, but each attempt uses one purchased voucher, so another voucher is needed for every additional try. Your topic-level performance report shows which areas to strengthen before retesting.
Results arrive within 36 hours on school days, with an overall score and a topic-level report. Successful candidates can download a certificate, which expires after 10 years.
