- The exam has 45 multiple-choice questions, a 90-minute limit, and a 60% passing score.
- Four official topic groups apply: Intro to the Internet, HTML, CSS, and Advanced HTML and CSS.
- Each voucher covers one attempt, and no reference sheet is provided for the Web Design exam.
What the Code Actually Means
If you landed here searching for the meaning of "CHS-WDES1," the short answer is this: on this site, it identifies the CodeHS Web Design Level 1 Certification. The label works as a compact shorthand. "CHS" points to CodeHS, and "WDES1" reads naturally as Web Design, Level 1. The issuer's own credential title is simply "Web Design Level 1 Certification."
It is worth stating plainly, because the same string of letters can appear in other contexts. Everything on this page describes one thing only: the CodeHS exam that tests foundational web design skills built around HTML and CSS. If you want parallel explanations of the label itself, our short pages on what CHS-WDES1 stands for and what CHS-WDES1 means cover the naming question from different angles, while What Is CHS-WDES1? gives a broader orientation.
Who Issues It and Why That Matters
CodeHS is both the governing body and the testing platform for this credential. That dual role shapes the whole experience. Exams are delivered through the CodeHS Certifications app, proctoring is handled through a Proctor Dashboard used by teachers or authorized proctors, and purchasing is organized around school and district vouchers rather than a typical open-market registration page.
This is a meaningful difference from certifications run by independent testing companies. Because the exam sits inside the same ecosystem as the CodeHS curriculum, the recommended preparation path is the CodeHS Web Design (Picasso) course or the Web Design and Development course. Both are described as recommended preparation, not eligibility requirements. You can read the eligibility details in our CHS-WDES1 requirements guide.
The Exam at a Glance
Here are the verified format facts in one place:
| Feature | CodeHS Web Design Level 1 |
|---|---|
| Question format | 45 multiple-choice questions |
| Time limit | 90 minutes, online, completed in one sitting |
| Passing score | 60% |
| Prerequisites | None required; Web Design (Picasso) or Web Design and Development recommended |
| Reference sheet | None provided for this exam |
| Accommodations | Extended time and read-aloud supported; other requests need platform review |
| Results | Within 36 hours on school days, with overall score and topic-level report |
| Certificate validity | 10 years |
One point of frequent confusion: the 60% passing score is a threshold on your own result, not a statistic about how many candidates pass. No official pass rate has been verified, and we do not invent one. For the scoring details, see our CHS-WDES1 passing score guide, and for a discussion of the data situation, read CHS-WDES1 Pass Rate: What the Data Shows.
Likewise, no official split between scored and unscored items has been verified, so avoid any claim that a certain number of your 45 questions "don't count."
The Four Official Topic Groups
The issuer's exam overview lists four top-level topic headings. These are official exam-topic groups, not a percentage-weighted blueprint and not a count of course modules. That means no one can honestly tell you that, say, CSS is worth a specific percentage of your score. What you can do is understand what each group covers and prepare across all four.
Domain 1: Intro to the Internet
The foundation layer. Candidates should understand how the web works at a conceptual level before touching markup.
- How web pages are delivered and viewed in a browser
- The relationship between a page, its files, and how they are named and organized
- The vocabulary used throughout the rest of the exam
Domain 2: HTML
The structural language of web pages. Expect questions on reading and interpreting markup, not only recalling tag names.
- Document structure and common elements
- Links, images, lists, and text-level markup
- Recognizing correct versus broken markup in a short snippet
Domain 3: CSS
The presentation layer. Candidates need to predict how styling rules affect elements.
- Selectors and how they target elements
- Properties for color, text, spacing, and layout
- Reading a rule and determining the visual result
Domain 4: Advanced HTML and CSS
The issuer expressly includes frameworks, user interfaces, accessibility, and multi-file paths in this group.
- Frameworks and building user interfaces
- Accessibility considerations in markup and design
- Multi-file paths: linking stylesheets, pages, and assets across files
For a deeper walkthrough of each area, our complete guide to all four content areas expands on the same headings.
What This Certification Is Not
Because the name is short and the field is crowded, it helps to draw boundaries. The CodeHS Web Design Level 1 Certification is:
- Separate from Web Development Level 1. That is a different CodeHS certification. This one is HTML/CSS-focused.
- Separate from course finals and projects. Completing a CodeHS course assignment or final is not the same as earning this certificate.
- Separate from teacher microcredentials. Those recognize educator skills, not student web design proficiency.
- Not an open-book or reference-sheet exam. No examination reference sheet is provided for Web Design.
For the most direct statement of the credential's identity, our CHS-WDES1 Certification overview and What Is CHS-WDES1 Certification? page complement this one.
Vouchers, Attempts, and Access
Fee mechanics for this exam run through vouchers. CodeHS provides school and district voucher pricing by direct quote, and no public numeric fee was verified. That is why you will not see a dollar figure here: quoting one would mean inventing it. The practical rules that do apply are:
- Each purchased voucher permits one attempt.
- Retakes have no numerical limit, but every additional 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.
The expiry rule is the one students most often overlook. If your school buys vouchers for the year, the time to use them is within that contract term. A voucher that sits unused into a new school year may simply be gone. Our certification cost breakdown goes into how to approach pricing questions, and the exam dates and scheduling guide covers the timing side.
Key Takeaway
Because retakes cost another voucher, treat your first attempt as the one that counts. Finish your readiness checks in the CodeHS Certification Practice course and our practice test before asking your teacher to schedule the exam.
Exam-Day Rules and Proctoring
The exam can be taken at home or at school, monitored by a teacher or authorized proctor through the CodeHS Certifications app and Proctor Dashboard. A few specifics deserve attention:
- One sitting. The exam must be completed in a single session within the 90-minute limit.
- Honor Code and randomized questions. You agree to an Honor Code, and questions are randomly selected.
- Focus Mode. This blocks navigation to other CodeHS pages. It is not described as a system-wide browser lockdown, so do not assume the rest of your device is locked, and do not treat that as permission to look things up.
- Prohibited behavior. External websites, collaboration, copying or sharing exam questions, and running code in another website or program are all prohibited.
- Allowed materials. CodeHS suggests paper, a pencil, and a calculator. There is no reference sheet.
The prohibition on running code elsewhere is especially relevant for a web design exam. You may feel tempted to paste a snippet into a separate editor to see what it renders. Do not. Build the habit beforehand of reading markup and CSS and predicting the result in your head, which is exactly what the exam rewards.
Results, Certificates, and Expiry
Results are released within 36 hours on school days. You receive an overall score plus a topic-level performance report, which is useful if you need to retake: it shows which of the four topic groups held you back. Successful candidates receive a downloadable certificate, and earned certificates expire after 10 years.
That 10-year window is long relative to how fast web standards evolve, so the certificate is best understood as evidence of foundational skill at a point in time rather than a statement about current tooling.
Who Benefits From This Credential
This is primarily a student-facing, school-delivered credential. Its natural audience includes:
- High school and middle school students finishing a CodeHS web design course who want a verifiable result beyond a course grade.
- Teachers and districts looking for a standardized, proctored measure of HTML/CSS skill across a class.
- Early-stage learners building a portfolio who want a documented first credential.
As for employment, be realistic. This is an entry-level, foundational certificate. It can support a portfolio, a scholarship or program application, or a conversation about your skills, but it does not by itself qualify someone for a professional web role, and we do not cite salary numbers for it. If you want to weigh the value, our worth-it analysis, CHS-WDES1 jobs page, and salary guide discuss how to think about it qualitatively.
Sequencing Your Preparation by Domain
Since the four topic groups build on one another, preparation order matters more than any generic technique. A simple progression follows the dependency chain. The CodeHS Certification Practice course for Level 1 is the official practice listing, but practice courses are not extra exam domains and do not establish official weighting.
Intro to the Internet and HTML
- Lock down vocabulary first, since later questions assume it
- Practice reading markup and spotting structural errors without running it
CSS
- Drill selectors and predict the visual outcome of short rules
- Rehearse working on paper, since you cannot run code during the exam
Advanced HTML and CSS
- Cover frameworks, user interfaces, accessibility, and multi-file paths
- Practice tracing how files link to each other across a project
Timed Review
- Run full 45-question sets against a 90-minute clock
- Revisit your weakest topic group and retest
Why leave Advanced HTML and CSS for third? Multi-file paths and accessibility questions assume you already read basic markup and styling fluently. A candidate who skips ahead often misses easy points on fundamentals while chasing harder topics. For a fuller plan, see the CHS-WDES1 study guide, the one-page cheat sheet for last-minute review, and our training overview. If you are wondering about difficulty, how hard the exam is addresses that directly.
When you are ready to test yourself under realistic conditions, our CHS-WDES1 practice test is built around the same four topic groups.
