I'm on deferred adjudication, will i get drug tested?

I was taken into custody by the school police for possession of a marijuana pipe (I'm 14) on my school bus. I got a citation because it was given to me to hide by a fellow student, got stuck with a class C misdemeanor, and now I'm on deffered adjudication. I took my drug class early on and I'm going back to court on the 25th. Will i be drug tested? They gave me notice last time i was on probation very early on, but that was when I had a probation officer, which I don't currently have. PLEASE HELP!
