Other Comments

From 1940 onward education was oralist, but changed to Total Communication in 1974; use of LESCO in the classroom started in the early 2000s. Interpreter training at the Universidad de Costa Rica. (2013 A. Oviedo). Two other sign languages among indigenous groups in the south (the Bribri and Boruca), apparently unrelated to LESCO (Woodward 1991).
