Some of these jobs may not require a regular 4 year degree, but they require at least a few years of school. There are training schools to get these degrees but they require you to stay in the program the entire time. You have to be able to prove your academic worth- able to communicate easily in English (writing and verbally) and pass certain entrance tests (essay, math, reasoning ect). Also you need a high school degree- Many frum high schools are not accredited!
OT and PT both do not require 4 years of undergrad to be able to enter the grad school, just the pre-requisite science and othermiscelaneous classes (depends on the school). They are each 2-3 years full time for the grad school. They make quite a bit as well.
