About Us

Our Story

Frisco International School is  a 21st century, multilingual, global and private school with a main campus in Frisco Texas. FIS is an on-campus and an Online School. 

We offer education to students from 10 to 18 years of age. The school was formed under the laws of the State of Texas, USA and started operations in February 2019. 

FIS Board of Directors recently decided to launched the Online School and is now accepting international minded students from anywhere in the world

Frisco International School is the passion and dream of our founder Professor Carlos Roncal. He has lived the values and the vision of what our school stands for. He has helped students at the local, national and international level experience what it means to be an internationally minded person and a life long learner.

Our school started in the mind of Prof. Roncal 20 years ago when he came to the Dallas area. He has since been teaching and promoting an international education as an educator, teacher and administrator at universities, private schools, pre-schools, public schools, charter schools, home schooling groups, Montessori schools and his own school.

Prof. Roncal finished the Lamar University School Principal Certification preparation course in December 2018, a year long course of study online. He is a graduate of ASU-Thunderbird Graduate School of Global Management and an education major from the University of Missouri, St Louis, He is a certified teacher in the States of Missouri, Texas and has completed many courses via Coursera from University of Maryland, University of California-Davis and the University of Houston.

Our Approach

Frisco International School prepares students to become internationally minded, bilingual and life long learners. We believe each student is different and must have a program designed specifically for her or him. Our school finds the talents in our students, encourages and develops such talents and creates the climate and environment for success in using those talents, 

Our students will be able to finish their high school credits in 2 years. They will have many options including being able to take AP (Advanced Preparation), take the dual credit. sit for the CLEP propgram and thus be able to get into college with several hours of credit. 

We are not constrained by standarized tests, bells or four walls. Our schedule is year round with breaks in between semesters. There is not summer forgetting and relearning the following September. This alone saves countless hours of actual learning. 

We believe young students should have a rigorous curriculum, should learn to think in a critical way and on a higher order. They should also learn the leadership values that has made our country whole for over 200 years. Our students will know what respect, integrity, kindness and hard work means and will become such a person.
