I cut n paste this, so look through it - some questions don't really apply, but I thought this was another good list....

Hiring Therapists:

Some therapy providers the supervisor and all the individual therapists who will work with your child each day.

Other providers may ask that you hire and manage the therapist team that works with your child. By taking this route, the hourly rate you pay can be cheaper. Management of a team takes a significant amount of work and coordination efforts.

Be sure to understand how your provider works and what they expect you to do in assisting your child’s program. Every program provides parent involvement at some level.

Finding good therapists: look for candidates who understand the program principles, have experience and LIKE children! Ask the same questions you would ask an experienced babysitter, including ask some additional questions like:

What experience do you have?
What training have you had? By whom?
How often do you attend follow-up training?
What books have you read or recommend on ABA?
How many families have you worked for? Why did you leave?
How do you work with difficult children misbehaving?
What are your 1 year and 3 year plans for the future?
Set up parameters on how to handle sick/vacation time
How long do you plan on working for my family?
Standard questions: Have you ever been arrested? Do you have a valid drivers license, how long have you lived at your current resident? Do you have a recent TB (tuberculosis) test? Can you please provide the test results?
Be specific on setting goals for discipline – discuss at the interview
Be specific on setting expectations for log and documentation – some therapist take 20 minutes each session for set up and documentation – discuss at the interview
Be clear on:
How much they are paid
Who pays them
How often checks are paid
Hourly rates (training rates, standard rates and weekend rates – if different – need to be clarified)
Be sure to use a therapist agreement between the family and the therapist.
Please provide 3 references – find out who these people are.
