Brantmeier [Brantmeier, C., 2006. Advanced L2 learners and reading placement: self-assessment, computer-based testing, and subsequent performance. System 34 (1), 15–35] found that self-assessment (SA) of second language (L2) reading ability is not an accurate predictor for computer-based testing or subsequent classroom performance. With 359 advanced L2 university-level learners, the present study attempts to provide new empirical evidence concerning the use of SA, when measured via criterion-referenced items, as a predictor of reading scores on a computer-based placement test and subsequent reading achievement. Before reading, participants completed a contextualized, criterion-referenced instrument for SA that was created from the European Language Portfolio. A four-item contextualized SA questionnaire was also completed after reading. Participants completed the following: self-assessment questionnaire taken prior to computer-based test, computer-based test of 8 readings, 2 in-class readings, written recall, multiple-choice, topic familiarity questionnaire, and post-reading SA questionnaire. Findings indicated that a descriptive and criterion-referenced questionnaire for SA may be a reliable predictor of both reading scores on a computer-based test and subsequent classroom performance when comprehension is measured via sentence completion and multiple choice items. The criterion-referenced questionnaire did not prove to be a reliable predictor of reading comprehension with the written recall task for the short story. The post-reading SA instrument proved reliable for all three comprehension tasks. Results hold important implications for both language placement directors and test constructors.
