Private schools and colleges make up a significant portion of the Polish higher education sector. There are approximately 310 private colleges and universities and 138 public colleges and universities in the city. This has resulted in unusual competitiveness, resulting in Poland having lower costs for considering than many other European countries to study in abroad. The higher education system is of great quality, and all of the top universities offer English-language projects in fields such as medical, engineering, humanities, business, and finance. Currently, more than 100 institutions of higher learning in Poland offer English-language study programs. The Bologna Process has seen Poland play an active role. The ECTS (European Credit Transfer System) allows students to be geographically mobile and continue their education in a variety of locations.
