<p>I think that’s incorrect. Each exam has a different pass rate. The teachers at our high school are pretty obsessed with knowing what the national average is and what their own personal pass rate is. They use those stats to see how well they are teaching the course. The school uses those statistics to assign teachers. If a particular teacher is well below the national average year after year, they try to get someone else to teach the course. For some tests, the national exam is about 50% and for some it’s higher than that and for some lower. But I’ve heard these stats quoted enough to know that 16% is not accurate.</p>
