My twins are just about to start yr 10 trial exams and study leave. This will last 2 weeks. My older children had trial exams in yr 10 but never study leave. It is apparently to get the students used to studying independently and exam conditions, although there has been talk that it will enable teachers to run extra revision classes for the yr 11s. I think missing 2 weeks of lessons in yr 10 is a terrible idea and this will be in addition to another set of trial exams in December when the grades will determine what tier exam the students will be entered for. I'm not sure if this will involve study leave as well.Is this common practice for yr 10s now?
