After establishing how many teachers depart from their teaching jobs and how these rates compare with other occupations, this chapter presents statistics on the reasons why teachers move from or leave their teaching jobs. These data are drawn from items in the Teacher Follow-up Survey (TFS) questionnaire that ask teachers to indicate the reasons (up to three) for their departures, from a list provided in the questionnaire (see Appendix). Data are presented from an additional set of items that asks teachers to indicate the sources (up to three) of their dissatisfaction, if they had indicated dissatisfaction either with teaching, their school, or their salary as a reason for their turnover. This free selection includes the Table of Contents, Foreword, Preface, and Introduction.
