The law specifies that your child must be assessed in all areas related to his suspected disability. If you or your child’s teachers have observed that he has behaviors which adversely affect school performance (for example, has poor impulse control, has problems making friends, or is withdrawn), you should request an assessment of your child’s social and emotional status as part of any assessment plan you sign.  [Cal. Ed. Code Sec. 56320(f).] You may ask for an assessment in this area even if the district has not identified it as an area for assessment on the assessment plan.  The district is required to use technically sound test instruments to assess the relative contribution of cognitive and behavioral factors and physical and developmental factors to the child’s disability and need for services.  [34 C.F.R. Sec. 300.304(b)(3).]
