The Social Entrepreneurship Performance Ladder (PSO) is a scientifically supported TNO quality mark. It is an instrument that provides insight into the extent to which organisations engage in above-average social entrepreneurship, focused on the employment participation of vulnerable groups in the labour market. The quality mark demonstrates that STE Languages ​​operates above average in a socially responsible manner by employing and supporting people who are overlooked in the labour market.

With our language training courses, we offer opportunities for personal and professional growth for students and companies, and in this way, we contribute to a more inclusive labour market and a society in which everyone participates. In the polarised world in which we live, this aspect is of great importance. The PSO quality mark also supports STE Languages’ mission: contributing to the integration of internationals in society.
