Why we invented Numbas

Bill Foster was director of the e-learning unit at Newcastle University until his retirement in 2016. In this post he tells the story of how Numbas came to be developed under his guidance.

Numbas is the latest in a long line of assessments systems: it is the spiritual successor at Newcastle to the i-assess assessment system which itself was based on the CALM system developed in the late 1980s.

In the following I will cover the implementation of CALM at Brunel University (1991/2), and at Newcastle University the implementation of i-assess (2006) followed by the development and implementation of Numbas (2012). 


Numbas features full documentation which is always in line with the most recent version.
