The results showed that the three instruments measured different dimensions of word recognition and predicted text comprehension. Text reading was the most robust indicator of comprehension and the most sensitive screener for weak readers. The diagnostic instruments provided interpretable feedback, located problems at specific areas, and evaluated instructional material difficulty level. The findings offer empirical support for the use of text reading for diagnostic purposes in Chinese low-level L2 reading instruction and suggest the importance of helping students develop word recognition skills.diagnostic assessmentword readingword segmentationtext readingChinese L2 reading comprehensionArticle
