Application status closed

I have applied for biology and science teacher but all of my application status are closed. I am masters in botany ( plant sciences) and teaching biology of high school grade 9 and 10 since five years . I am also teaching science in high school of grade 8 ' grade 7 and grade 6 . I have a license of teaching which never expires but they didn't consider my application. Please guide me what should I do. I could not understand what to write in references. Please guide me in this regard as well.
Best regards
