Dear Parents/Guardians, Students, and Faculty,
Sintra International Christian Academy would like to thank you for your support and patience as we have all worked to adapt to multiple changes during this uncertain time. We are a great team with an exceptional school family and are forever grateful for your support and faithfulness.
To our graduates, best wishes as you head off and continue your journey beyond high school. You have contributed greatly to our school and will always be a part of the SICA family. To the members of our community who are moving, we wish you the best as you venture out into the world and hope that you will always remember your time here at Sintra International.
After concluding online classes for the elementary grades and presencial classes for the secondary grades, we have emailed report cards to parents throughout the weeks. If you have not yet received your child’s report card please reach out to the office by sending an email. If you have not yet enrolled or re-enrolled your child(ren) for the 2020-21 school please reach out to the office in order to receive the new enrollment form.
Here at SICA we would like to wish you all a blessed summer vacation and would like to encourage you to stay safe during these uncertain times. We are looking forward to seeing all of our returning students and of course new students this Fall.
We are a new K4-12 International Christian Academy with an American curriculum. We opened our doors in September 2017. We provide a rigorous traditional curriculum while teaching 21st Century skills. Our College Prep program prepares students to excel in their SATs and attend American or international universities. Our small class sizes allow for individual attention. Please see our Academics page for information about our program. We also offer sports and other extracurricular opportunities.
Providing academic opportunities through an inspiring, creative, positive, and character building learning environment.

Sintra International Christian Academy is operated by Comunidade Cristã Evangélica Adonai's Ministry of Education and guided by Christian values and excellence in education. The Academy is a vision project launched by Senior Pastor Americo F. Marques that seeks to inspire in our children a love for learning, a sustaining Christian faith, respect for a diverse world, and a call to service. We create a welcoming community that encourages each individual to grow in confidence, creativity, integrity, and compassion, grounded in the knowledge that each is a child of God.
Sintra International Christian’s vision is to create a passion for learning and discovery in a supportive, Christian environment. All students are encouraged to dream, explore, and experiment, as they grow into the children God has created them to be. Our faculty and staff are committed to helping each student develop the self-confidence, self-discipline, and self-respect necessary for strong character
development and academic success. Sintra International strives to empower its students to be responsible members of the school community and the world.
We look forward to hearing from prospective families, so feel free to visit during normal business hours. Please call for an appointment or send an email to
