Grammaggio is a free app that contains a variety of grammar tasks based on research on the condition of Specific Language Impairment (SLI), a language disorder that delays the mastery of language skills in children who have no hearing loss or other developmental delays. Along with your score, Grammaggio will tell you how you compare to others your age. The Grammaggio app was developed as part of a program of research on SLI. The research is funded by R01DC001803 and R42DC013749. This study did not study the validity of the screening for children speaking African American English (AAE). We express our appreciation for the participation of more than 1,000 people (children, siblings and parents) who have contributed to this longitudinal research project and to the dedicated research staff.
