According to Earl McGee, the superintendent of school, “My suggestion would be ‘Nemaha Valley Schools’ since the valley starts at Corning and runs past Kelly and Seneca.” On December 14, 1966, the Seneca Public High School was condemned. From 1967 to 1969, high school classes were held at the City Hall building, the Masonic Temple, and at the Seneca Grade School. Several bond issues to build a new school failed to pass election. Much of the disagreement centered around the location of the new high school. Some supported a central location for the three towns, while others favored building it in Seneca. In 1968, this disagreement eventually led to Corning transferring to the Centralia, Kansas school district. After Corning left the Nemaha Valley District, the high school bond issue specifying a new Nemaha Valley High School at Seneca passed. The old Seneca Public High School was demolished on July 1, 1968. In 1969 the new Nemaha Valley High School opened for classes. During this same year, Kelly High School was closed, and its students attended NVHS. In March 1970, Nemaha Valley High School was dedicated. In 1974, Saints Peter and Paul High School closed. In 1979, Kelly Junior High closed, and in 1981, Kelly grade school closed. During this time, a new Onida grade school and high school and Bern High school opened in the district. This addition of students required expansion of the buildings. In 1983, the north wing on the grade school was added, and in 1993, the west wing of the grade school was added. The north wing is now the junior high. The west wing primarily houses elementary grade classes. On March 10, 2007, the old section of Seneca Grade School was destroyed in a fire. For the remainder of the school year, classes were held in the public library annex in the basement of Bowman Law Office and Dental Practice, at the former restaurant Bob’s Sirloin, and at the high school. A bond issue to build a new grade school and junior high school passed in November 2007. The new school was to be located south of the high school. Nemaha Central USD 115 formed in 2011 by the consolidation of Nemaha Valley USD 442 and B&B USD 451. On May 2014, state budget cuts resulted in closing of the neighboring B and B High School in Baileyville, Kansas. Those students were transferred to Nemaha Valley High School. This prompted a school renaming the preceding year, with students in grades 7 through 11 at Baileyville, students in grades K through 11 in Nemaha Valley, and students in Saints Peter and Paul Catholic School voting to change the name to Nemaha Central.
