Is it Fisher Family Trust (FFT) you actually want?
You could google it but you may wish you hadn't; It really doesn't have any meaning to those of us who are just parents.
Please don't get too hung up on all these Cats things. They have limited, if any, value to (just) parents. I'm sure your DS is doing well and if he's not then I'm sure the school will soon tell you.
The only beneficial thing (for us as a family) to come from any of mine doing CATS was (them) learning what sort of learner they were. Audio, visual etc. which later helped them pick specific revision techniques for exams.
