Imus Unida Christian School (IUCS) was founded in 1968 when key members of the Imus Unida Church believed that expanding the church ministry into a school can be a great opportunity to continue to share the Word of God to the community. At first, the classes were held in a few rooms around the church area. Legally, when it started to operate in 1968, it was presented as an extension of the church’s Sunday school until 1980. In 1981, it gained recognition from the Dept. of Education as a preschool. Through the support of generous partners of the church members, in 1996, the first building of the IUCS was constructed and the school expanded to be able to serve students from Nursery to Grade 6.
In 2006, IUCS celebrated its first batch of high school graduates. Additional floors were then added to accommodate high school students. IUSC fully operated a complete K-12 program in SY 2016-2017. In the year 2019, the student population of Imus Unida Christian School was about 1,200.
