PPA stands for planning, preparation and assessment, and it is the time allotted to teachers in order to plan lessons and reflect on what works well and what does not with his or her classes. Most schools give teachers free periods for this time.

There is some confusion about whether or not PPA refers to a specific type of teacher, such as a teacher's assistant. PPA is not a specific person or type of teacher, although coaches who excel in maximizing the time allotted for PPA are sometimes referred to as PPA coaches. In general, the acronym refers to the time given to teachers for planning.
