The primary benefits of the Fast ForWord reading program are improvements in reading and language skills, although results vary for each student. One 2013 study found that the program showed positive results for students with language-learning impairment.
Improvements in reading and language skills occurred in non-randomized studies, where the researcher compared student performance before and after using Fast ForWord. Randomized studies of Fast ForWord have not proven it to be effective.
The 2013 study found that students with language-learning impairment improved in all oral language measurements after using the program. Fast ForWord uses speech-sound drills with words that have altered sounds. These drills can make it easier for those with slower temporal processing to understand the words.
