This article reports findings from an investigation of the factor structure and reliability of the High-Level Language Aptitude Battery (Hi-LAB), an innovative test for predicting high-level attainment in post-critical-period second language acquisition. The introductory section motivates the need for a new test of second language aptitude and briefly describes Hi-LAB's conceptualization, constructs, and computer-delivered format. Then the hypothesized Hi-LAB factor structure is tested against empirical data (n = 163). Finally, the reliabilities of Hi-LAB tasks are estimated and reported, using both internal consistency and test-retest correlation techniques. For the most part, the empirical data are in line with the hypothesized aptitude constructs, and most tasks met or exceeded criteria for reliability.
