CodeHS Practice Test

High school students take CodeHS certification exams to show their skills in areas such as Python, Java, web design and cybersecurity, and adults in the workforce can take them too. This page explains the exam format and rules as CodeHS publishes them and matches each exam to our free practice sets. It also works through sample questions that we wrote ourselves. They are not taken from the real exam.

What the CodeHS is and how it works

According to CodeHS, “Each exam is timed at 90 minutes and contains 45 multiple-choice questions.”^[1]

CodeHS has a range of certification exams, and each one covers a single subject at a set level, such as Python, Java, web design or cybersecurity. Each exam lasts 90 minutes and has 45 multiple-choice questions. You must finish it in a single sitting. You take it online, at home or at school, with a voucher your teacher gives you. There are no specific prerequisites, so adults in the workforce can test as well as students.

To pass, you need 60% on every exam except Java, where the passing score is 50%. CodeHS shares results within 36 hours of finishing the exam, and only school days count toward that time. A test taken just before a weekend or holiday may therefore take longer to come back. You can retake an exam as many times as you need, but every attempt needs its own purchased voucher. CodeHS does not publish a list price. Schools get a quote from CodeHS sales. A certificate you earn expires after 10 years.

Some things vary by school: voucher pricing, which exams your school offers, and how your teacher schedules attempts. For anything not covered here, check the CodeHS Help Center articles on certification exam format and the certifications FAQ. Those are the official sources for the facts on this page.

CodeHS content outline and where to practise each area

The content areas below are copied from the official CodeHS content outline published by CodeHS. The right-hand column shows which of our practice sets covers it.

Worked examples: how to reason through CodeHS questions

These are practice questions written for this site, not questions from the real exam. Each explanation shows why the right answer is right and why the others are wrong.

Example 1

Question: What does 'professional boundaries' mean in the context of a teacher-student relationship?

1. Maintaining appropriate distance in all personal and digital communications
2. Refusing to help students outside of class hours
3. Only communicating through official school channels about grades
4. Limiting instruction to exactly what is in the curriculum

Answer: A. Maintaining appropriate distance in all personal and digital communications

Explanation:

A is correct. Professional boundaries mean a teacher keeps an appropriate distance from students in every channel: in person, by email, in messages and on social media. The aim is to keep every interaction appropriate and transparent. It is not about holding back help.

• B is wrong: Helping students outside class hours through approved routes is normal and does not cross a boundary.
• C is wrong: It shrinks boundaries down to grades and official channels. A teacher can talk about many topics and still keep boundaries, and can break them even on an official channel.
• D is wrong: It mixes up boundaries with how much of the curriculum gets taught.

Rule to remember: boundaries are about the nature of the relationship, not about how much help or content a student gets.

Example 2

Question: Which coding language is primarily taught in CodeHS's introductory Python curriculum?

1. Python 3
2. Python 2
3. Jython
4. MicroPython

Answer: A. Python 3

Explanation:

A, Python 3, is correct. CodeHS introductory Python courses teach Python 3. It is the actively maintained version of the language and the one new learners are expected to use.

• B is wrong: Python 2 is an older version that is no longer supported. It also differs in details, for example print is a statement rather than a function.
• C is wrong: Jython is an implementation of Python that runs on the Java Virtual Machine. It is a way of running Python, not the version taught in an intro course.
• D is wrong: MicroPython is a slimmed-down Python for microcontrollers. Some hardware projects use it, but it is not a main teaching language.

Rule to remember: questions about modern introductory Python point to Python 3. Names like Jython or MicroPython describe implementations, not versions of the language.

Example 3

Question: Which action constitutes a breach of client confidentiality?

1. Sharing client information with unauthorized parties without consent
2. Discussing a case with a supervisor for consultation
3. Documenting information in the secure client record
4. Reporting suspected abuse as required by law

Answer: A. Sharing client information with unauthorized parties without consent

Explanation:

A is correct. Confidentiality is breached when client information reaches people who have no right to it and the client has not agreed.

• B is not a breach: Asking a supervisor for advice is an accepted, need-to-know use of information within the professional relationship.
• C is not a breach: A secure client record is exactly where confidential information is meant to be stored.
• D is not a breach: Reporting suspected abuse when the law requires it is a legal exception to confidentiality.

Rule to remember: ask who received the information, and whether consent or legal authority covers that disclosure. The same reasoning applies to student records in a school.

How to use these practice tests

First, confirm with your teacher which CodeHS exam you are taking, because each subject has its own exam. Then read the official exam format and FAQ pages so you know about the 90-minute limit, the 45 questions and your passing score before test day.

1. Do an untimed round in the matching practice set from the table above. Note every question you miss or guess.
2. Go back to the related CodeHS course units and rework those topics. Write and run small programs instead of only rereading notes.
3. Return to the set and retry the questions you missed until you can explain why each wrong option is wrong.
4. Close to test day, take the practice test under timed conditions in a single sitting. This lets you practise the pace the real exam needs: 45 questions in 90 minutes.
5. Before the real exam, check your device, your login and your voucher with your teacher.

If you do not pass, use your results to find your weakest topics. Then repeat the cycle and arrange a new voucher for the next attempt.
