Technical assistance is provided concerning documentation of functional vision loss for Florida students with visual impairments. The functional vision observation should obtain enough information for determination of special service eligibility. The observation is designed to supplement information on the medical eye examination, and is conducted by a teacher of visually impaired students or an appropriately trained diagnostician. Components of a functional vision observation include medical eye examination information, developmental and functional visual response information, and notation of classroom modifications required. The paper contains a four-page functional vision observation form, and 13 bibliographical references with annotations. (JDD)
