Sorry ~ Jargon ...... CPD is for teachers, lecturers and the like. It stands for Continued(ing) Professional Development ~ something that everyone in Education has to complete annually. A full time teacher, for example, must complete 30 hours CPD each year (what do you thing all those inset days are for?) and must maintain a file of their annual participation in qualifying courses, workshops etc. Part time teachers/lecturers (Like Mrs S#2) must complete a pro-rata amount of CPD each year. In Mrs S#2's case it is something like 14 hours pa.
Mrs S#2 has to produce her file of evidence to Estyn inspectors when they visit her classes. Estyn is the Welsh version of Offsted.
