However, the report notes: «Despite the relatively low numbers of principals reporting unfilled vacancies in individual curriculum areas, there are still fairly large numbers who report that they have difficulties in suitably filling staff vacancies across all areas of the curriculum.» (teachermagazine.com.au)
