One thing that is frustrating to Michelle and her colleagues nationwide is when applicants ask questions about timelines. One young man called and needed instantaneous employment; we had to explain that this is a hiring process. The application is the first step, then written tests, and so forth. One step is dependent upon the previous step. There are no promises. Ask about the process and follow it.
I had one applicant who stated that he was going to be on his honeymoon the week of the physical agility and wanted to know if he could he take it later—No. Point here is that agencies set these tests up for their staffing and needs, not your nuptials.
Most agencies will give you the state certifying authority Websites for the state requirements. I strongly recommend you visit the Website(s) and ensure you meet your respective state's requirements. Unfortunately, I have seen some candidates that started the process but were removed due to medical requirements. Corrected/uncorrected vision is one that catches many; read the requirements. Without going into too much detail, each state is different in sight, hearing, and physical standards. Not to mention the psychological requirements. Make yourself very familiar here.
I am not here to frighten off any possible recruits. Hey, we need you! But it is your responsibility to fully read the job requirements, become familiar with the application process, and apply them to your situation. It costs a department hundreds of taxpayer dollars to process a police applicant. Maybe it is the frugal side of me, but I don't want to waste the money or your time.
Train Hard and Train Smart.
