It was the only state art school in the Province of Posen. In 1916 it was renamed Academy of Arts and Crafts and was part of the higher study cycle of the university, as were the two Music Schools. The Academy has survived unchanged in Bydgoszcz till 1920. Interwar period (1920-1939) After Bydgoszcz was reunited with the revived Polish state in 1920, the school was renamed National School of Arts and Crafts, with the same curriculums. The director of the facility was the architect Kazimierz Ulatowski. Professors were recruited among the artists, from other regions of Poland, and from abroad. Thus came to Bydgoszcz: painters Jerzy Rupniewski, Bolesław Lewańsk; sculptors, painters and medalists Bronisław Bartel, Jan Wysocki and Feliks Giecewicz (who both had Piotr Triebler and Teodor Gajewski as students); graphic designers Karol Mondral, Piotr Chmura, Leon Dołżycki (who had Franciszek Gajewski as student); graphic artist Antoni Procajłowicz. They were at that time the most prominent representatives of various artistic trends. University of Bydgoszcz was one of only four universities in the country with such a profile.

The state authorities, contrary to city initiative, decided that in times of reconstruction of the country, the nation needed more artisans than artists: consequently, Art school closed down and in its place was established in 1923-1924 the National School of Industry. Director of the new school was engineer Franciszek Siemiradzki, the school having two divisions: Technical; Arts and crafts, for carpenters and locksmiths. A year later three other departments opened: Agricultural industries, for trained farmers; Graphics industry; Craft industry. Between 1926 and 1931, the building also housed a Civil Aviation Mechanics School (). After a reorganization in 1931, the school consisted of two departments:Chemistry industry and Mill industry. It was the only institution in Poland educating professionals in this latter field. The average attendance was about 400 students, with a low below 300 students during the Great Depression. Pupils were coming in majority from outside Bydgoszcz, it is only in recent years that city students are more numerous. Therefore, in the 1930s, the school had its own dormitory at 11 Nowodworska in the Szwederowo district until 1935, . The Industrial School was soon famous
