[3] The closest school for the Deaf was located in Copenhagen, Denmark and called Det Kongelige Døvstummeinstitut, the Royal Institute for the Deaf-Mute.

Through financial support from the county's Department for the Poor in Trondheim, Møller began his studies at the school in 1810 at 14 years old.

He did exceptionally well in several subjects and in 1815 began to learn woodworking on the lathe;[4] that year he was put to work as "teacher and répétiteur for the oldest class of students" by the head of the school, Norwegian-born doctor and professor Peter Atke Castberg.

From 1815 to 1817 Møller primarily resided in Trondheim, where he taught Deaf students from his father's home.

[6][7] Castberg encouraged Norwegian authorities to open a school for the Deaf in Trondheim with Møller as teacher.

The suggestion was well-received, and the Bishop of Nidaros, Peder Olivarius Bugge, forwarded it to the Ministry of Church Affairs, at the time responsible for education, with his recommendation.
