In general, the documentation should:
- Be provided by a licensed professional, qualified in the appropriate specialty area; the report should be on letterhead, dated and signed.
- Include both diagnostic information and an explanation of the current functional limitations of the condition. It should be thorough enough to indicate whether or not a major life activity is "substantially limited," that is it should explain what the extent, duration, and impact of the condition is
- In most cases, it should be relatively recent; a suggested guideline is less than 3 years old. Documentation of conditions that are permanent or non-varying (e.g., a sensory disability) may not need to be as recent, but some chronic and/or changing conditions require even more current information to provide an accurate picture of functioning.
- Be detailed enough to support the accommodations that are being requested. Accommodations are determined by assessing the impact of the person's disability on academic or work performance.
- For a variable or progressive condition, include the degree and range of functioning.
- Address the impact of medication or other treatments on major life activities.
