how can you tell if the A/C clutch is bad vs. compressor is bad? on 2001 Ford Escort

A/C not turning on. I want to recharge it but the compressor does not engage.

If it is low enough or out of freon the compressor will not kick in. Put some freon in, it will take it without comptessor running, then see if it will work. If that dosen't do it ckeck for voltage and ground at compressor wire connector. You may need asistance, if so get some.
