Details

The CASLO approach is a high-level template for designing qualifications that is both outcome-based and mastery-based.

Outcome-based approaches insist qualifications should be designed around learning outcomes. Mastery-based approaches insist that only those students who have demonstrably mastered the full domain of learning should pass the qualification.

The CASLO approach - so called because CASLO qualifications are designed to Confirm the Acquisition of Specified Learning Outcomes - came to prominence in England during the 1980s and into the 1990s with the introduction of National Vocational Qualifications.

This report sets out to explain how and why the CASLO approach was first introduced in England, how it came to dominate the Technical and Vocational Education and Training landscape, and why it began to fall out of favour with policy makers in recent years. It aims to identify what lessons can be learnt from this trajectory.
