No.  A federal Office of Special Education Programs Clarification Letter written January 14, 1992, states:

• Neither Part B nor Part B regulations provide for any exclusions based on intelligence level in determining eligibility for Part B services…All children, except those specifically excluded in the regulations, regardless of IQ, are eligible to be considered as having a specific learning disability, if they meet the eligibility requirements… [18 IDELR 683.]

In addition, school districts cannot deny assessment for special education eligibility solely on adequate grades. Grades are only one indicator of the educational impact that a student’s disability is having on the student’s school functioning.
