Summary and Conclusions:Summary and Conclusions:
1. For many older children with word level reading skills around the 1. For many older children with word level reading skills around the 30th percentile, a relatively brief (60hrs) dose of appropriate small 30th percentile, a relatively brief (60hrs) dose of appropriate small group instruction can bring their skills in phonemic decoding, text group instruction can bring their skills in phonemic decoding, text reading accuracy and fluency, and comprehension solidly into the reading accuracy and fluency, and comprehension solidly into the average range.average range.
2. For many older children with word level reading skills around the 2. For many older children with word level reading skills around the 10th percentile, a more substantial dose (100hrs) of appropriate 10th percentile, a more substantial dose (100hrs) of appropriate small group instruction can bring their skills in phonemic decoding, small group instruction can bring their skills in phonemic decoding, text reading accuracy, and reading comprehension solidly into the text reading accuracy, and reading comprehension solidly into the average range. Although the gap in reading fluency can be closed average range. Although the gap in reading fluency can be closed somewhat, reading fluency is likely to remain substantially impaired. somewhat, reading fluency is likely to remain substantially impaired.
3. For older children with word level reading skills around the 2nd 3. For older children with word level reading skills around the 2nd percentile, intensive interventions can have a strong effect on percentile, intensive interventions can have a strong effect on phonemic decoding, text reading accuracy, and reading phonemic decoding, text reading accuracy, and reading comprehension, but they are likely to leave the fluency gap essentially comprehension, but they are likely to leave the fluency gap essentially unaffected.unaffected.
