SJB provides an excellent culture academically and spiritually. We are incredibly impressed with the entire teaching staff. Each teacher is dedicated to assuring the success of each child. Class sizes are small and intimate. The curriculum is tough and advanced. 90% of kids graduating SJB end up in IB/AP high school programs. The school has awesome sports, art, Spanish and music programs as well. We couldn't imagine our children outside of this amazing environment.

St. John's is a great school. I have sent four kids through St. John's, and the opportunities they had in academics, art, sports and Spanish far surpass what I had as a kid, even though I went through a very good public school system. The school is also excellent at developing faith-filled Catholic young people who understand how to treat others and how to follow Jesus Christ.

We couldn't be happier with our experience at St. John the Baptist Catholic school in Longmont. The SJB family is welcoming, faith-filled, and positive. We have three children enrolled at SJB. While we live in unincorporated Boulder County (closer to Niwot), the kids have friends from many of the near-by cities (Frederick, Firestone, Berthoud, Erie, Lafayette). Our youngest attended the pre-school last year two are currently at the elementary school and our oldest attends the middle-school. This K 8 institution provides an excellent education with rigorous academics, but it's the catholic education, small class size, and faith-based approach that we appreciate most. The curriculum is focused (AP/IB prep), provides a solid approach to all subjects (religion, Spanish language, science, math, English, music, literature, physical education) and has strong sports programs (including widget sports programs).

My children have attended St. John the Baptist Catholic School for the past two years. SJB boasts small class sizes and rigorous academics. Pre-school incorporates religious education in all aspects of learning while grades K-8 have a specific class for religion. In addition, they offer specials classes such as art, physical education, music, and Spanish, some starting in pre-K. The teachers and staff genuinely care about each and every student, which makes for a strong sense of community. The school has made such a name for itself that students are drawn from area communities, such as Firestone, Frederick, Berthoud, and Erie. SJB is an excellent choice for anyone looking for a school that develops the whole child.
