In January 1963, Republic Act No. 3705 converted the Ilocos Norte Normal school into the Northem Luzon Teachers College (NLTC). In 1977, it offered a four year education course. By the year 1974-1975, there was a need to provide a laboratory high school for the student teachers, hence the Bureau of Public schools approved the creation of the NLTC Laboratory High School. In 1976, NLTC was named Northern Luzon State University (NLSU), hence the high school was also name NLSC Laboratory School. When the college eventually became the College of Education of the Mariano Marcos State University (MMSU) under P.D. 1279 in 1978, the high school was named University High School Laoag.
