A free JavaScript web page (DOM) test for Year 9 (ages 13–14): 12 questions, marked instantly – predict, write and fix real web-page code. No sign-up. This test is for Year 9 (ages 13–14).
Before you start
12 questions on querySelector(), textContent, new elements, classes, style and click events, picked from a bank of 54 each time. Each question shows a small web page and some JavaScript. Some ask what it prints or which error it stops with; in others you write or fix code that changes the page. When you write or fix code, press Run to try it. It is marked when you move on: your program is run in your browser against the example and some hidden tests on other web pages. Choose Practice to see the answer after each question, or Test to see your answers at the end.
- 12 questions – a new mix each time you try
- JavaScript runs in your browser – nothing to install
- A keyboard helps for the coding questions
No sign-up and no adverts. Your answers and your code stay on this device. Nothing you type in the test is sent to us – unless you choose to report a problem with a question.
How it is marked: Classfern's own checks, in your browser. Code is run in a locked box against tests, some of them hidden; nothing is marked by a person or by guesswork. Spot a mistake? Use the Report button.

Curriculum: the key stage 3 computing programme of study says pupils should be taught to use 2 or more programming languages, at least one of which is textual, to solve a variety of computational problems; make appropriate use of data structures [for example, lists, tables or arrays]; design and develop modular programs that use procedures or functions; and to create, reuse, revise and repurpose digital artefacts for a given audience, with attention to trustworthiness, design and usability.
