The International S-Series "Schoolmaster" was a Type C (conventional) bus chassis manufactured by International Harvester, which became Navistar during its production run. It was introduced in 1979 as the replacement for the Loadstar bus chassis; it was used for both school bus and commercial bus applications. In 1989, it was replaced by the International 3800; both chassis were offered that year. The Schoolmaster was the last bus chassis designed by International Harvester.
The Schoolmaster used powertrains and components from the S-Series medium-duty trucks. Two models were available: the S-1700 and the heavier-duty S-1800.
The Schoolmaster changed relatively little over its production run. Many of these changes reflected the change from International Harvester to Navistar. In 1987, an updated International logo was added to the grille and the steering wheel. Also, in an industry first, all gasoline engines were dropped from the S-Series bus chassis powertrain lineup. In 1989, Navistar heavily upgraded the S-Series trucks, which had become the 4000-Series. The bus chassis was redesigned from the firewall forward and the entire dashboard was replaced. The new-generation bus chassis was called the 3800, which was produced into 2004. As such, the 3800 was the final S-Series variant to conclude production.
Alongside the conventional, International also offered a stripped chassis for Type D (transit style) school bus manufacturers. The 1853-FC (FC=Forward Control) was powered only by diesel engines. In 1989, the 1853FC was replaced by the 3900, which Navistar used until 2010.
