As early as 1510, a schoolteacher is believed to have taught classes in Kübelberg, even though the village did not yet have any schoolhouse. In 1615, the Reformed pastor Nicolaus reported to the "Oberamt" of Kaiserslautern: "At Kübelberg is a schoolmaster, Petrus Matzenbach. Has a salary from the Collector of 30 Rhenish guilders … also seven "malter" of corn. … This schoolmaster is hardworking, good at his calling …". During the Thirty Years' War (which began only three years after Pastor Nicolaus’s report), schooling fell by the wayside, and it only began again once many children began growing up in the families that came to settle the village after the war. In Schönenberg and Kübelberg, schooling took different directions in each village. Kübelberg, as a new Catholic parish, established in the early 18th century a Catholic school, though the schoolteacher had to wait a long time for his monetary and material emoluments, since according to the rules, there was still supposed to be a Protestant schoolteacher. The Catholic school also sought out Catholic children from the neighbouring villages, mainly from Schönenberg. The building of the Catholic schoolhouse in Kübelberg about 1705 was financed by the pastor himself. Until then, school was taught at private houses or at the rectory. In 1754, the "Schultheiß" reported to the "Oberamt" that the Catholic schoolmaster in Kübelberg had to teach 60 children and received 10 "Malter" of corn and 25 guilders each year, lived in a small, not well-built house and had at his disposal a little garden. About the children’s behaviour there was no complaint. Given the steady population growth, the available schoolhouse soon was no longer big enough for the village. In 1797, the people of Kübelberg got a new schoolhouse for all the area’s Catholic children. In this building, which would later become the convent, school was taught until 1910. In 1848, the municipality bought up the inn to convert it into a school, too. The number of Catholic children rose more quickly than the number of Evangelical children, and thus Schönenberg soon found itself having to make an equalization payment to Kübelberg. The year 1965 marked the last time that a school for Kübelberg alone stood on Pestalozzistraße in Kübelberg.
