Which aspect is assessed through invigilated tests?

The aspect that is assessed through invigilated tests is the integrity of the assessment process. Invigilated tests are conducted under strict supervision to ensure that all candidates adhere to the examination rules and maintain fairness during the assessment. This supervision helps prevent cheating and guarantees that the evaluation accurately reflects each candidate's abilities and knowledge.

While content knowledge retention is relevant to the overall purpose of an assessment, invigilated tests specifically focus on ensuring that the assessment process is secure and credible. Peer collaboration would undermine the integrity of the test, as it allows for sharing answers, which is not permissible during an individual assessment. Time management skills may be a component of taking the test, as candidates need to complete their work within a given timeframe, but the primary role of invigilation is to uphold the integrity of the testing environment.
