The use of the THRASS program with younger children with literacy difficulties

As a practising teacher, I was given the responsibility for choosing a program to use with a group of children of mixed ages who were experiencing difficulties in literacy learning. The program selected was THRASS. To justify its continued use I needed to determine: - whether the program was effective in helping these children develop their literacy skills, and - whether improvements could be made to the conduct of program and/or its assessment procedures.
