From January 2, 2020, teachers can apply in the Lectors 2020/202 Program organized by the National Agency for Academic Exchange (NAWA).

NAWA is inviting teachers of Polish as a foreign language who would like to work in one of over 80 academic centers in the world.
Candidates are expected to have appropriate substantive preparation (e.g. studies with a glottodidactic specialization) and work experience, as well as such features as openness to other cultures, readiness to take on new challenges, the ability to organize a workshop, high personal culture and communication skills.

Teachers delegated by NAWA to foreign universities will teach Polish and introduce Polish culture, history, art and science to the Polish students, as well as to support the Agency in information and promotion activities.
