As the population grew, so did the variety of trade goods and handicrafts produced in the city. In the 14th century, there were 30 different types of goods produced in the city, most of which are cloth or canvas goods. Economic prosperity gave rise to a mentality that valued education, which prompted the 1528 opening of a new school building. In the 15th and 16th centuries, 150 Bieczan students studied at the Jagiellonian University in Kraków, then still known as "Akademia Krakowska". Most of these students returned to Biecz after completing their studies.
