Ser preperado o estar preperado?
Cual es la diferencia?
5 Answers
Ser preparado would indicate that the person is always prepared; it is an intrinsic characteristic. To me this would be unlikely.
Estar preparado would indicate readiness for a particular thing.
Su tarea está preparado. His homework is prepared (done).
As Delores stated, the use of "ser" would indicate a more permanent status... saying that the person has the characteristic of always being prepared.
The use of "estar" would indicate a more tempory status... saying the person is prepared or was prepared for something in particular.
Like Lazarus, I am not a fan of the "permanent/temporary" theory. It works, sometimes, but so does flipping a coin. It can also fail spectacularly (Lazarus has provided many examples in various threads).
I cannot conceive of circumstances in which I would say "Él es preparado" (even when speaking of a boy-scout). I might say "Nuestas comidas son preparadas por nuesto chef (jefe de cocina)." but that's a simple passive construction having nothing to do with permanent/temporary.
El está preparado.
Hi teel512 and welcome to the SpanishDict forum!
You might be interested in reading this article regarding the differences between Ser and Estar. It was written by a well-respected member who has also gained a reputation for being something of a "grammar expert" on other language learning sites as well. I hope that it can help to clear up some of the confusion for you 
HI teel, have a look at this reference article too.
