L2tasoja

L2tasoja is a standardized framework for evaluating second-language proficiency across languages. It provides a unified set of proficiency levels, cross-domain skill definitions, and reporting conventions intended to improve comparability of results between assessments, courses, and institutions.

The framework models proficiency along multiple dimensions: listening, reading, speaking, and writing, plus interaction and mediation. Each dimension is described using a common set of level descriptors, with behavioral indicators and example tasks for calibration.

L2tasoja includes an ontology that links tasks, rubrics, and assessment instruments to level descriptors. It supports metadata for tasks (difficulty, context, modality) and enables interoperable data exchange between learning management systems and assessment engines.

Usage and impact: Educational programs use L2tasoja to align curricula with assessments, to report progress to students, and to permit transfer of results across institutions. It is designed to be compatible with existing frameworks while providing a language-neutral representation of proficiency.

History: The framework was proposed by a consortium of universities and language testing professionals in the early 2010s and has since been described in academic resources and demo deployments.

Critiques and limitations: Potential challenges include the resource requirements for calibration and ongoing maintenance, the risk of over-standardization at the expense of local context, and the need for widespread adoption to realize interoperability.
