Since our academy does not offer pre- pretest, we find it hard to know how much of an education they have until maybe mid course. However, we offer a pre-test on the material that they will be learning.It's not till later that we learn that some cannot comprehend just the readng or math to say. This makes teaching a little difficult. I do not rush through the material. My quote is "leave no one behind" but sometimes I have no choice when its 2 days later and they still have not gotten the material. I do an early evaluation and have the Program Director involved to help out.
