| The primary outcomes of the study are various tests used in practice to test reading and spelling levels. In the context of dyslexia, these tests are used to diagnose dyslexia and assess the effectiveness of treatment (i.e., improvement scores on these tests).ReadingDrie-Minuten-Toets (DMT) or three minute test is a well-validated and commonly used test to assess reading speed in the Netherlands throughout primary school (6-12 years old). It can be used in education as standardized test material or in the cases of reading impairment, to diagnose dyslexia in conjunction with other measures. The test consists of 3 sheets of increasing difficulty, each containing five rows of 30 words. The child is asked to read as many words as quickly and accurately as possible in one minute (per sheet). The first sheet contains one syllable words that are phonologically transparent, which are either CV, VC or CVC words. The second sheet contains one syllable words, with six different word structures: CCV, CCVC, CVCC, CCVCC, CCCVC, or CVCCC. The last sheet contains words with two to four syllables (i.e dreamy or kitchentable) (Wouda, 2017). The DMT is administered at T0, T2 and T3. To compute a reading score, the raw number of correctly read words of the three sheets are combined into a sum score, with possible scores ranging from 0 to 450 (30 words * 5 rows * 3 sheets), with higher scores reflecting higher reading level.SpellingPI-Dictee is a well-validated spelling test commonly used to assess spelling abilities of individuals at risk for dyslexia. It can be used in education as standardized test materials to track the spelling level in a classroom or as a way to signal impaired spelling skills (Boom test onderwijs, 2013). The test consists of nine blocks of each 15 words, with each block increasing in difficulty. The child hears the words verbally. After each word, they are instructed to write the word independently. Which blocks are used depends on the didactical age of the stude | — |
