What type of tests are designed to identify strengths and weaknesses in language?

The type of tests designed to identify strengths and weaknesses in language learning are Diagnostic Language Tests. These assessments specifically target areas where learners may struggle or excel in their language skills, providing educators with detailed insights into a student's current level of proficiency. This allows for more tailored instruction that meets the individual needs of students.

In contrast, Language Achievement Tests primarily assess the extent to which students have learned a specific language curriculum, not focusing as much on diagnostic information. Proficiency Tests are generally intended to evaluate a learner's overall language ability, often used for certification purposes or to assess performance against a standardized measure. Formative Assessments are ongoing evaluations used throughout the learning process to monitor student progress and understand areas needing improvement but do not take on the diagnostic specificity that Diagnostic Language Tests provide.
