There is no such thing as Asst ATCO so presumably you want to become an Air Traffic Control Assistant? (Maybe be called somethig else depending on the ATC unit). ATCOs are licenced like pilots but ATSAs are not.
I don't know how much you know but outside of NATS ATC assistants may not earn too much, but again this depends on the unit.
