Is Numbas just for maths testing?

Not at all. While Numbas’ design makes it extremely useful for maths testing, it can be adapted for a range of tests. Organisations and schools worldwide have already started adapting it subjects such as chemistry, psychology, company skills-testing, and zoology.

What makes it different?

Many testing systems can be pricey, complicated or inflexible. Numbas is set up to allow users to start creating their own tests quickly, and to share them with students without headaches.

Educators can set up a free account and choose from a public database of questions, or start creating their own. When they have put together their test, they can share it to places where students are already learning.

Exams can be shared to a wide variety of locations, online and offline, and can be viewed on tablet, mobile or desktop.

What is Numbas?

Numbas is a web-based e-assessment system that helps users create online tests. It was designed with numerical tests in mind, but is equally suitable for a range of other subjects.

Numbas was developed at Newcastle University. However, teachers in schools, universities and companies around the world are now using it to measure the progress of their students and employees.
