You should request a reevaluation.
Reevaluation should occur every 3 years unless you and the school agree otherwise. You can request a reevaluation as often as once a year. If you need to have a reevaluation sooner than a year you and the school agency need to come to an agreement regarding the need for the reevaluation.
Also, make sure your child is taking the medications the doctor has prescribed. Make sure you give the child the medication as the doctor told you to.
If you feel the medication is not working you should talk to your doctor’s office immediately so the medication can be adjusted. You should not independently without talking to the doctor first change or stop giving the child his/her medication. Of course, if the child has a bad reaction to his/her medication you should take her to the closest emergency room as soon as possible.
