In 1899, the Plano Independent School District became a separate entity from the city. Because of this separation, 1899 is cited by the district as the establishment date for Plano Senior High School. Starting in 1901, the school was affiliated with the University of Texas, Baylor, Texas A&M, and Southwestern in order to ensure that graduates could secure entrance to college. Unfortunately for students, official affiliations eventually ended due to budget restrictions. However, the affiliations, coupled with the high standards of Plano schools, led to a large number of graduating students going on to attend college. By the mid-1910s, a majority of the graduating class (as much as eighty percent) matriculated to an institute of higher learning, such as the University of Texas at Austin or Baylor University. According to the 1915 "Plano Review", "The University of Texas probably draws more students from Plano than any one other institution." The Review goes on to state that "no town in Texas, in proportion to its size, has more students in higher institutions of learning than Plano."
