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

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
