TUCSON, Ariz. (AP) — A new report says teaching vacancies throughout Arizona have increased by more than 150 positions compared to last year. Arizona Daily Star reports that the Arizona School Personnel Administrators Association released the report last week saying a quarter of teaching positions in the state are vacant. The report identified 1,846 vacancies out of the 209 school districts and charter schools that participated in the statewide survey. The survey found about 1,000 teachers statewide either abandoned or resigned from their teaching positions during the first half of the school year. The report also found that about 4,000 or half the teaching positions are filled by teachers who do not meet the state’s certification requirements.
