Sectiontwo focuses on the first component of the framework anddescribes the categories that are relevant to produce acomprehensive descriptive account of the teacher policiesthat are in place in a given education system. Sectionthree, in turn, focuses on policy guidance. It reviews thosepolicies that, based on the available evidence to date, areknown to matter most to improve student outcomes. Itdescribes in detail the evidence supporting each of thesepolicies, as well as the ways in which high performingeducation systems combine them to ensure outstanding studentoutcomes. The document concludes presenting an account ofhow the framework is expected to evolve as new evidence onteacher policies becomes available.
