Education is the foundation of a country. School-based assessment is a new policy venture in the highly centralised education system of Malaysia. The Malaysian education system, having gone through several different development eras, should be making adjustment according to changing demand. The Malaysian Government introduced SBA or its Malay acronym PBS (Pentaksiran Berasaskan Sekolah) as part of the National Transformation Programme to produce world-class human capital.

It also aims to reduce exam-oriented learning among learners, evaluate learners’ learning progress and enhance teachers’ integrity in assessing, recording and reporting of learners’ learning (KPM, 2012).

However, it always concerns information on learning and learning acquisition, which is about whether and what people have learned. The purpose of assessment is constantly changing. Robertson (2005) suggests two ‘traditional’ reasons for assessment which are mainly for communicating results of student achievement which has been a key responsibility for teachers, and selecting and sorting students for entry into various programmes.

Heady (2000) suggests assessment tools should be “able to demonstrate continuous improvement” and help students focus on their own learning while the measurement methods should be consistent,
