Standards Referenced Reporting (SRR)

Five levels of performance: 5 (highest) to 1 (threshold) + unclassified5 (highest) to 1 (threshold) + unclassified5** (best performance) and 5* (next best group)Standards at levels 5 and 4 are set with reference to grades A-D of current HKALEComponent levels for Combined Science electives will be reported in the certificate

Standards setting

A candidate’s total subject score is based on both public examination and SBA resultsA panel of judges (experienced teachers, markers, examiners etc) will determine the minimum examiners, etc) will determine the minimum scores (cut scores) a candidate must obtain in order to meet various standards (Levels 1-5)

HKDSE Bio School-Based AssessmentPrinciples of SBA design:

integrate assessment with teaching and learning

align with curriculum aims (e.g. develop the ability to

make scientific inquiries) by addressing curriculum emphases and learning targets (e.g. make careful observations, formulate hypothesis for investigation)

feedback for better learning and teaching

HKDSE Bio School-Based Assessment

Implemented in 2 phases:

2012 & 2013 Exams

Moderation of SBA mark

a statistical moderation method will be adopted The “school” would be used as the unit for moderation

Sthe average and the spread of SBA scores of students in a given school will be adjusted with reference to the public examination scores of the same group of students students’ SBA marks may be adjusted but the rank order determined by the school will remained unchangeddistrict coordinators will also inspect samples of the district coordinators will also inspect samples of the students’ assessed work to assist moderation and make adjustments if necessary
