Standards Referenced Reporting (SRR)

Five levels: 5 (highest) to 1 (threshold) + unclassified

5** (best performance) and 5* (next best group)

Standards at levels 5 and 4 are set reference grades A-D of current HKALE

18

Standards setting

• Based on examination results, candidates are awarded with a total score

• To determine the minimum scores (also known as cut scores) a candidate must obtain for meeting various standards (Levels 1-5)

19

Overseas Recognition

Sample Papers sent to CIE for overseas moderation

Recognition sought from overseas assessment authorities

Marked scripts for some subjects (Eng, LS, 1 Science and 1 Humanities subjects) will sent to CIE for vetting

Draft Level Descriptors (as of Nov 2008)

Level 5

demonstrate comprehensive knowledge and understanding of facts, concepts and principles in the curriculum

design and conduct scientific investigations, evaluate procedures, handle and analyse data collected, and draw valid conclusions

21

Level 4

demonstrate sound knowledge and understanding of facts, concepts and principles in the curriculum

apply the concepts of science to unfamiliar situations

analyse, synthesise and evaluate information from several perspectives

communicate ideas in a logical and coherent manner using scientific terminology and appropriate formats

design and conduct scientific investigations, handle and interpret data collected, and draw conclusions

22

Level 3

demonstrate adequate knowledge and understanding of facts, concepts and principles in the curriculumapply the concepts of science to unfamiliar situations with guidanceconstruct relationships and analyse informationcommunicate ideas in a clear, structured manner using scientific terminology and appropriate formatsdesign and conduct scientific investigations, handle and interpret data collected, and draw conclusions with guidance

23

Level 2

25

Features of SRR

• The standards are held constant

• The percentage of students awarded a given level may vary from year to year

• The standards are more informative

• Level descriptors together with students examples can better reflect the standards
