At the top end of the spectrum, teachers with values of ten on the overall index, which corresponds to benefitting from two-thirds of the identified best practices, are likely to rank among the top half of all teachers. As Figure 2.3 shows, teachers who benefit from fewer than two best practices of teacher professionalism are likely to rank among the bottom third of all teachers in terms of their perceived status and satisfaction, they are much less likely to report that they believe teaching is valued in society and that they are satisfied in their work environment and with their profession, in general. They are also less likely to be confident about their teaching (self-efficacy), although the impact is less pronounced: even teachers in schools that use fewer than two best practices fall within the 35th percentile of all teachers. In contrast, those benefitting from roughly two out of three practices are likely to be in the top half of the distribution, all other factors held constant.
