Last year, I was a per diem sub teacher in two different districts and I got 5+ different school districts wanting to interview with me. This year, I’m a permanent sub and part time teacher in one school district building and have only gotten 3 interviews. Do these schools want less experienced teachers? I was not offered one job due to my lack of classroom experience last year. What can I do to stand out on my resume? Should I enter competitions and complete more certifications? TIA
