A major part of SLTI’s work lies in the development of foreign or second language proficiency tests for a variety of clients, including private corporations; federal, state, and local government agencies; and educational institutions.
SLTI develops customized instruments tailored to the client's needs. Second language proficiency tests may assess one or more of four communicative skills: listening, speaking, reading, or writing. Although these skills are interrelated, they are nonetheless distinct. SLTI can also assist clients who are involved in test development projects.
SLTI also develops specialized language tests, such as tests of translation or interpretation ability, or language for specific purposes (e.g., language for doctors, for engineers, or for the classroom).
No matter the type of language test, the test development process is broken down into a series of proven, discrete steps, as illustrated in the figure below. Click on the figure for more information on the steps in the test development process.
