The language is official along the Aguaytía, San Alejandro, and Súngaro rivers in Perú where it is most widely spoken. It is used in schools until third grade. There are not many monolinguals, although some women over the age of fifty are.
There is five to ten percent literacy compared to fifteen to twenty-five percent literacy in Spanish as a second language. A Cashibo-Cacataibo dictionary has been compiled, and there is a body of literature, especially poetry.
