This area of the platform presents a number of tests that assess linguistic skills of signers in five sign languages:
LSC (Catalan Sign Language), LSE (Spanish Sign Language), LSF (French Sign Language), LIS (Italian Sign Language) and ISL (Israeli Sign Language).

These tests evaluate comprehension and production of isolated signs and of full sentences.

Click on the corresponding sign language to be directed to the corresponding page, where you can read a short description of every test that is available for that language.

You can download here a detailed description of each test, including validation and piloting procedures.

Please find here a document containing guidelines and recommendations on how to use these assessment tools and on more general issues concerning sign language policy.

Our tests are available for free. If you are a researcher and you would like to use them, please contact us.

Note that these are not yet clinical tests and they are intended to be used only in a research environment. We plan to develop some of these tests into clinical tools in the near future.

We have used these tests to collect data from 3 groups of Deaf participants: Native signers (exposed to sign language from birth); Early signers (exposed to sign language before the age of 6); Late signers (exposed to sign language between the age of 6 and 15). The results so far indicate that an early exposure to sign language has a positive impact on several language skills.

Stay tuned, we shall soon upload the first papers reporting our results!
