A particularly hot topic in the field of education is the issue of its financing, ie the scale of funds actually needed and their sources of financing. Are there effective methods of measuring the necessary resources in education and is the Polish model organizationally distant from the best practices? How expensive are any changes? What should be invested in in advance to build a modern education system meeting the challenges of the 21st century? What are the greatest weaknesses of the Polish education model and is money alone able to solve these problems?
