Three research questions were addressed regarding the reliability, the validity and the sensitivity to growth of the Maze scores. The participants were 96 students (44 girls; 51 boys; 1 unknown sex) across four school years enrolled in a Dutch secondary school for practical education. The relation between the CBM Maze scores and two criterion variables (a reading comprehension test Nieuwsbegrip and School Grades for Dutch) was examined. In addition, beginning-and-end-of-year mean Maze scores were examined in order to determine whether the scores were sensitive to growth. Positive and moderately to strong correlations provide support for the reliability of the Maze scores. The present data, however, provide only minimal support for their validity. Finally, results suggest the Maze scores were sensitive to growth.Show less
