From the IDEA:

(7) Parent counseling and training means-

(i) Assisting parents in understanding the special needs of their child;
(ii) Providing parents with information about child development; and
(iii) Helping parents to acquire the necessary skills that will allow them to support the implementation of their child's IEP or IFSP.

(ii) The services and placement needed by each child with a disability to receive FAPE must be based on the child’s unique needs and not on the child’s disability.

(h) In evaluating each child with a disability under §§300.531-300.536, the evaluation is sufficiently comprehensive to identify all of the child's special education and related services needs, whether or not commonly linked to the disability category in which the child has been classified.

(b) Remedies for denial of appropriate services. In resolving a complaint in which it has found a failure to provide appropriate services, an SEA, pursuant to its general supervisory authority under Part B of the Act, must address:

(1) How to remediate the denial of those services, including, as appropriate, the awarding of monetary reimbursement or other corrective action appropriate to the needs of the child
