Problems with ASL as a last resort..
Frank Bowe (1991) in Approaching Equality reiterated that deaf children seem to reach a plateau at third grade reading comprehension levels. Furthermore, it is widely acknowledged that there has been a noticeable lack of improvement in raising this reading level and other achievement levels of deaf and hard of hearing students. Despite over 30 years of research into American Sign Language and its status as a language on par with other languages of the world, there is ongoing reluctance in the United States to capitalize on deaf children's bilingual, bicultural capacities in promoting literacy and achievement. While it is well-documented that achieving solid competence in a fully-accessible first language provides a basis for becoming literate in other languages (Collier, 1989; Cummins & Swain, 1986; Krashen, 1982; Mahshie, 1995; Svartholm, 1994), deaf children in the U.S. are regularly denied access to a language they can fully master during their preschool years, postponing a great deal of learning and development (Collier, 1989; Cummins, 1979; Newport & Supalla, 1987). It is not uncommon to find deaf high school students who, after years of failure with other methods, are finally given access to American Sign Language (ASL) late in life, and are struggling in high school with language levels in both English and ASL that would be comparable to those expected as normal for preschoolers.

See the red...I see it happening here on AD as well.
