I try my best and I don't know what else to do??

 can you get on  permanent? I'm not sure how to get them to call you back, sounds like your doing all I can think of, sorry....I hope someone has better advice for you.

When I was a sub I had to call all the schools I wanted to work at and put myself on their list....other than that it's hoping teachers ask for you specifically.

It must be pretty competitive eh? I personally pray about everything. I would do this above all.

My daughter is a teacher.  The teachers do not hire the subs, or the TA's--the school does.  And the school rarely asks the teacher for their input.  

I am a temp Dental Hygienist.  If a client likes me and asks for me again, that's all well and good, but that client may not need a temp again for MONTHS.  What you need to do to work continuously, is to impress the agency that places you.  To do that, you need to be available on short notice, be willing to take WHATEVER and WHEREVER the assignment is, and never complain or make demands.  Show up on time, be professional, and work your tail off.  A client who COMPLAINS about you, for whatever reason, will burn your chances of placment with ANYBODY.  After you have shown your worth, you will have more likelyhood of getting better locations or assignments.

Edited to add: Sign up with multiple agencies or school districts.  This will increase the odds of someone calling you for an assignment.

 I'm not sure, sounds like you are handling it well, bump!

My wheels are spinning I think what I can also do is email the school and tell them I'm subbing and my qualifications. Also when ever I sub stop at the office and drop my name off and phone number and say If you ever need a sub here's my name and number....

This is good advice for yourself.  Already have  your thinking juices going. Good job!  It's what I would have suggested myself. :)

Try subbing in all the school districts in your area. Get on their lists.

How do the districts work calls for subs? Do they just call you? Some will post on a site the night before, and the first sub to respond gets the job.

Your best bet is to also volunteer as much as you can, so HR, the principals, and the principals' assistants know your face.

I'm a teacher. My friend just got her master's in special education and is just now receiving callbacks for LTS positions. She's been trying since May. It's tough out there.

We have a program AESOP which I personally don't like AESOP will post. It is first come first serve

Sometimes a school can call you and have you come in.

Maybe they don't need you and that's why they haven't called?

If you're a sub, they only call you when they need someone.
