In many countries, less experienced teachers (those with less than five years' teaching experience) are more likely to work in challenging schools and less likely to report confidence in their teaching abilities than more experienced teachers. Most countries have activities in place aimed at preparing teachers for work, such as induction and mentoring programmes. Approximately 44% of teachers work in schools where principals report that all new teachers have access to formal induction programmes; 76% work in schools with access to informal induction; and 22% work in schools that only have programmes for teachers new to teaching. Fewer teachers report participation in induction and mentoring programmes than principals report the existence of such programmes.
