As a freshman at St. Joseph High School, Towns led the basketball team to a state championship in 2012, earning himself the top position in the ESPN 25 national ranking of high school players. Towns also led his team to state titles in 2013 and 2014. Towns was selected at the age of 16 to play on the Dominican Republic national basketball team, which represents that nation in international competition. Towns was eligible based on the fact that his mother is from the Dominican Republic. During 2011 and 2012 competitions, John Calipari, head coach at the University of Kentucky and a former NBA head coach, coached the team, which finished third in the 2011 FIBA Americas Championship and fourth place at the 2012 FIBA World Olympic Qualifying Tournament for Men, falling one position short of qualifying for the 2012 Olympic Basketball Tournament.
