What You Are Actually Paying For
When people search for the cost of the CodeHS Cybersecurity Level 1 certification (CHS-CY1), they usually expect a single price tag. In practice, the total cost of earning this credential is made up of a few separate pieces: access to the exam itself (delivered through a voucher), any preparation resources you choose to use, and the cost of any additional attempt if the first one does not go your way.
This article breaks down each of those pieces using only what CodeHS has actually published. Where a number is not public, we say so plainly rather than guess. If you are still getting oriented with the credential itself, start with What Is CHS-CY1 Certification? and then come back here to plan your budget.
The exam you are budgeting for
CHS-CY1 is the CodeHS Cybersecurity Level 1 certification exam. It is an online, timed exam made up of 45 multiple-choice questions. According to the CodeHS Certifications FAQ, the exam is timed at 90 minutes and the passing score is 60%. Those format details matter for cost because they determine how much preparation you realistically need before spending an attempt.
What CodeHS Does and Does Not Publish About Fees
The two official sources for this credential are the CodeHS Cybersecurity Level 1 Certification overview and the CodeHS Certifications FAQ. Neither of those pages lists a dollar amount for the exam. That is an important point, because many third-party sites publish confident-looking prices for credentials that share a similar-sounding name. Those figures belong to other programs and should not be applied here.
What is confirmed

Voucher Mechanics: Why Every Attempt Needs a New One
The single most budget-relevant rule in the CodeHS certification program is that a new voucher is required for each exam attempt. A voucher is how access to the exam is granted, and it is consumed when you use it. That means your cost planning should treat each attempt as a distinct purchase or allocation rather than assuming one payment covers unlimited tries.
What this means in practice
- One attempt, one voucher. Passing on the first try is the cheapest path by a wide margin.
- A retake is a new expense. If you do not reach the 60% passing score, going again means obtaining another voucher.
- Who pays can vary. In many cases a teacher, school, or program may be the one distributing vouchers. If you are a student, ask your instructor how vouchers are handled before assuming you will pay out of pocket.
Key Takeaway
Because each attempt consumes a voucher, the smartest cost-control move is not shopping for a cheaper exam. It is arriving at your attempt prepared. Use practice questions to confirm readiness first, then spend the voucher.
Building Your Real Budget
Since the exam fee is not publicly listed by CodeHS, a useful budget is built from categories rather than invented numbers. Here is how to think about each one.
1. Exam access (voucher)
This is the one line item you must confirm directly. Ask the teacher, school, or CodeHS representative who is managing your access how vouchers are obtained and who covers them. Write the answer down before you begin studying so there are no surprises.
2. Preparation resources
There are no prerequisites for CHS-CY1, which means you can technically sit the exam without taking any course. However, CodeHS recommends its Fundamentals of Cybersecurity course as preparation. If your school already provides that course, your marginal prep cost may be close to zero. If not, factor in whatever access to that material costs you, plus any practice tools you choose.
3. Practice testing
Free and low-cost practice is the highest-leverage spending in this whole process, because it lowers the odds that you burn a second voucher. You can start with the free question sets on the main practice test site to find out where you stand before committing to an attempt.
4. Contingency for a retake
Because every attempt needs a new voucher, a sensible plan reserves room for the possibility of a second try, even if you hope never to use it.
| Budget Category | Required? | How to Handle It |
|---|---|---|
| Exam voucher | Yes | Confirm price and who pays with CodeHS or your instructor |
| Fundamentals of Cybersecurity course | Recommended, not required | Check if your school already includes it |
| Practice questions | Optional but valuable | Start with free sets, add more only if gaps remain |
| Retake voucher | Only if needed | Plan for it, aim never to use it |
Where Prep Money Pays Off Most
The exam covers six domains, and the official sources do not publish percentage weights for them. That detail changes how you should allocate time and money: without weights, you cannot safely skip any domain. A weak spot in one area can cost you the points you need to reach 60%. For a full walkthrough, see CHS-CY1 Exam Domains: Complete Guide to All 6 Content Areas.
Domain 1: Cybersecurity Essentials
Conceptual and vocabulary-heavy, so it responds well to cheap or free review.
- Ransomware and phishing
- Internet of Things and the CIA Triad
- Cyber ethics, credit and copyright
- Legal vs. illegal hacking
Domain 2: Cryptography
Often the most hands-on domain. Practicing the actual ciphers saves you from a costly miss.
- Basic cryptography and code breaking
- Brute force and frequency analysis
- Caesar cipher and Vigenere cipher
Domain 3: System Administration
Worth reviewing with real exposure to a command line rather than only reading about it.
- Operating systems, software and software licenses
- Application security and browsers
- System administration and the command line
Domain 4: IT Concepts
Networking fundamentals that reward understanding over memorization.
- Internet addresses, IPv4 and IPv6
- DNS hierarchy and routing
- Packets and protocols
Domain 5: IT Infrastructure
A broad hardware and networking survey where recognition of terms matters.
- Internal components and peripheral devices
- Network devices, storage options, network options
- Network communication and network management
Domain 6: Digital Safety and Data Security
Mixes everyday safety topics with technical items like SQL.
- Digital footprint, cyberbullying, internet safety
- Clients and servers
- SQL queries, SQL injection, developer tools
Because every domain is fair game, a free diagnostic across all six is the most cost-efficient first step. Our CHS-CY1 Study Guide: How to Pass on Your First Attempt walks through how to sequence this, and the CHS-CY1 Cheat Sheet is a fast way to check recall before test day.
Retake Planning Without Overspending
A retake is where cost quietly doubles, so it is worth understanding what a pass actually requires. The passing score is 60%. On a 45-question exam, that threshold is a modest bar compared with many professional credentials, but it still leaves little room if an entire domain is a blind spot. You can read more about the threshold in CHS-CY1 Passing Score: Exactly What You Need to Pass.
Signs you are not ready to spend a voucher
- You consistently miss questions from the same domain, such as cryptography ciphers or SQL injection.
- You can recognize terms but cannot explain them, for example describing the difference between IPv4 and IPv6 or how DNS resolves a name.
- You have not practiced under the 90-minute time limit.
Value Over the 10-Year Credential Window
CodeHS states that certification credentials expire after 10 years. From a cost perspective, that is a long validity period: a single successful attempt gives you a credential that remains current for a decade, rather than something you must renew every year or two. That makes the effective cost per year of validity low relative to many credentials that require frequent renewal.
Setting honest expectations about return
CHS-CY1 is an entry-level credential covering foundational cybersecurity concepts. It is best understood as proof of baseline knowledge, which can support a student's portfolio, college applications, or movement toward more advanced study such as CodeHS Cybersecurity Level 2. It does not carry published salary data, and we will not pretend otherwise. If you want to weigh whether it fits your goals, read Is the CHS-CY1 Certification Worth It? and CHS-CY1 Jobs for a grounded view of where it helps.
Key Takeaway
Judge cost against purpose. For a student building foundational skills, a credential valid for 10 years that requires no prerequisites can be a low-friction addition. For someone expecting a direct salary jump from this single exam, the credential alone is unlikely to deliver it.
A Domain-Based Prep Schedule That Protects Your Budget
If you want to minimize the chance of a second voucher, a short, domain-ordered plan helps. The goal is to put the hands-on domains early, when you have the most time to practice them, and to finish with a timed full-length run.
Foundations and Cryptography
- Cover Cybersecurity Essentials: ransomware, phishing, the CIA Triad, ethics
- Work through Caesar and Vigenere ciphers by hand, plus frequency analysis and brute force
Systems and Networking
- Review operating systems, software licenses, browsers, and command line basics
- Study IPv4 vs. IPv6, DNS hierarchy, routing, packets and protocols
Infrastructure and Data Safety
- Cover internal components, peripherals, network devices, storage and network options
- Practice SQL queries and recognize SQL injection patterns; review digital footprint and internet safety
Timed Readiness Check
- Take a full 45-question practice run within 90 minutes
- Revisit any domain where you fell short before using your voucher
