What the pass rate does and doesn't tell you

It is an average across everyone who tested in that period. It is not your personal chance of passing.
A lower pass rate than ASP or CSP does not prove the CHST is "harder". The candidate groups have different backgrounds and eligibility rules.
BCSP publishes the pass rate in its annual report. Check the next report for updated numbers.
