In 1912, Dr. Lund left the Baptist Missionary Training School and it was closed. Following that year, in 1913, Dr. Valentine's objectives were realized and in the same year the Jaro Industrial School also admitted its first female student; it was fully incorporated then by the Philippine government and enrolled 740 students. Then in 1915, Jaro Industrial School opened its first high school program, starting with first and second year classes, adding third and fourth year classes in 1920. As the both two schools were founded by the Northern American Baptists from the American Baptist Churches, ordination for women is affirmed that resulted and eventually in 1917, the Jaro Industrial School elected its "first female head and Principal", Mary J. Thomas, who tenured as a Principal of the Jaro Industrial School from 1917 to 1918. The Baptist Missionary Training School later however was reopened in 1913 by Rev. Alton Bigelow. It was under Rev. Alton Bigelow's leadership that the Bible School began to have a definite direction in its development. In 1921, the following year after the Jaro Industrial School added fourth year high school classes, the school graduated its first high school batch.
