As a result of constant reorganizations and efforts at centralization, there were time and again space problems, and frequent teacher turnover. Eventually, eleven classes were being taught at the Pfeffelbach school, but the changes were not over yet. Soon, the upper classes were all grouped into the "Hauptschule Kusel", and now there was only the primary school left in Pfeffelbach. In Kusel, students can also attend vocational schools and other kinds of secondary school. There are also special schools for children with learning difficulties or mental handicaps. The nearest university town is Kaiserslautern (Kaiserslautern University of Technology). Pfeffelbach today has one kindergarten and one primary school. Pfeffelbach has a multipurpose hall. Pfeffelbach lies on "Landesstraße" 349, which leads from Thallichtenberg by way of Pfeffelbach to the state boundary with the Saarland. Running southwest of the village, but within municipal limits, is the Autobahn A 62 (Kaiserslautern–Trier), with an interchange some 3 km west of Pfeffelbach. A railway between Kusel and Türkismühle by way of Pfeffelbach (the "Westrichbahn") was in service from 1936 to 1969. Its trackbed nowadays serves as a cycleway and footpath. Kusel station is on the Landstuhl–Kusel railway served by Regionalbahn service RB 67, which uses part of the "Glantalbahn" and runs through to Kaiserslautern.
