This is a 1EdTech standard to allow platforms used for assessment to integrate more easily with tools used for proctoring candidates taking assessments on those platforms. Using the Proctoring Specification a candidate can launch out from their assessment platform to the proctoring tool, initiate a proctored session with that tool, and be returned securely back to the assessment platform to take the assessment while being proctored by the proctoring tool. This standard also provides a method for proctoring tools to send messages to the assessment platform during the assessment to control a candidate’s progression including, if necessary, a facility to terminate the assessment. This standard is based upon LTI Advantage.
