If you have the time and energy, try to volunteer time for your child's school. Volunteers can free up some of the teacher's time. This may, indirectly, give her more time to focus on your child's needs. This also gives the parent an opportunity to get to know the school environment and some of the child's classmates. Having a good knowledge of the functioning of your child's school can help clear up potential misunderstandings.
Some parents choose to arrange for private evaluations or tutoring.
Speech therapy, occupational therapy and some other services may be covered by some insurance plans. Some companies have dependent medical care plans which allow the parent to put pre-tax money aside for medical and child care expenses. This can be used to cover certain kinds of assessments and treatments not covered by insurance or paid by the school. Check with your employer or tax specialist. Many private schools have arrangements with tutors and speech therapists.
