Classroom performance assessment has gained prominence parallel to the multiplicity of the purposes ahead of assessment. Of many, the major controversy, which was the motive behind this study, is the incorporation of L1-based elicitation as a valid measure of second language (L2) performance assessment. To shed empirical lights on this issue, this explanatory sequential mixed-methods research employed 87 Iranian intermediate EFL learners, whose L2 classroom performance was assessed through L1-based elicitation techniques. In order to validate this mechanism, multi-method mono-trait model (namely, Pearson correlation, structural equations, exploratory and confirmatory factor analysis, composite reliability and convergent validity) suggested by Henning and Mesick’s Unitary Concept of validity were applied. The results from these multiple sources of evidence yield support to their common consensus that L1-based elicitation techniques are valid measures of L2 performance assessment. The findings then offer legacy to the educational implications of L1-based mechanisms both in L2 instruction and assessment.
