Other studies have focused on assessment practices in specific regions, such as UNESCO’s work on the Asia-Pacific (UNESCO, 2012a). Still others have focused on the more technical issues of assessment, such as the recently revised guidelines by the American Psychological Society, the American Educational Research Association and the National Council on Measurement in Education on standards for educational and psychological testing (AERA, APA and NCME, 2014). The latter is an important reference work for good assessment practice both in terms of technical quality and as regards fairness and ethical testing.
