The following table is a 'quick look' table containing publishers of assessments (formal and informal assessments), therapy materials and books. The list is not exhaustive and many new products are introduced (and some withdrawn), so please visit the individual web sites for more information. There are also tools available fro preventative / screening by other professionals which are not listed here. Also note that speech and language therapists are primarily interested in phonology in terms of speech, rather than literacy, although these are of course related.
