This is a handbook designed to help readers understand more about language assertiveness (LA) and learn about resources that can be used to promote it. It is designed for all minority language speakers but it can also easily be used to help trainers design valuable resources which will boost the confidence of their students to use the language naturally and confidently in various social contexts. The handbook is intended to be used as part of the Trainers' Toolkit of the LISTEN project (https://listen-europe.eu/trainers-toolkit/).

This work was funded through the project LISTEN (Linguistic Assertiveness for Minority Language Speakers) by the Erasmus+ Programme of the European Union under Grant Agreement No. 2019-1-ES01-KA204-064957.
