[Evaluation of the Marburg Spelling Training (MRT) in 2nd- and 3rd-grade students with spelling difficulties].

Objective: Children with severe dyslexia are substantially impaired because reading and writing are key competencies necessary for a successful academic and occupational career.

Methods: In this evaluation study, a cohort of 2nd- and 3rd-grade students from a variety of Hamburg primary schools was trained with the Marburger Rechtschreibtraining (MRT) by supervised university graduates. The research questions focused on the feasibility of the MRT as a within-school training, the improvement of spelling and reading skills of the participants, subjective assessments of success, as well as potential predictors.
