It was formed by the merger of the Hancock-Avoca Community School District and the Shelby Community School District on July 1, 1996. In 2012 the A-H-S-T district and the
Walnut Community School District began partial-day-sharing, in which students went to one school for some courses, as well as sharing of athletic programs. In 2014 the district began whole grade-sharing, in one school district sent its children to another school district to attend schools there all day. Circa 2015 the middle school area of the AHSTW Secondary School building in Avoca was scheduled to receive an expansion. The election for the school district merger was scheduled for September 8, 2015 after the
Green Hills Area Education Agency approved of the merger proposal and election. On July 1, 2016, the A-H-S-T district merged with the Walnut district to form the
AHSTW Community School District. ==References==
