Antonian uses MBS Direct to provide information and purchasing options for textbooks used for Antonian courses. Students are responsible for the purchase of their own textbooks. If a textbook is noted as "required," it is imperative that the student acquire the book and bring it as directed by the teacher.


Antonian College Preparatory High School is on a four-quarter grading system. Students receive progress reports at the end of each quarter. All grade reports can be found in the Ascender Parent/Student Grade Portal.

For purposes of extracurricular participation status, student progress is monitored at each quarter-end. Students who are failing more than one course at each quarter-end are placed on the ineligibility list. A student may earn removal from the ineligibility list at the mid-quarter point (approximately 4 1/2 weeks) of the subsequent quarter or the end of the subsequent quarter.

These students may practice, but they may not participate in any competitive event or performance. These students may not wear uniforms or attend a game or event in any capacity other than as a spectator.



At Antonian, we take pride in our commitment to academic excellence. Our dedicated faculty and staff work tirelessly to provide a dynamic and enriching educational experience that prepares students for a successful future.


Our courses are carefully crafted to meet state and national standards while also catering to individual student needs and interests. From core subjects to advanced placement and honors courses, we offer a wide range of academic options to cater to diverse learning styles.


Education goes beyond textbooks, and at Antonian, our core values are an integral part of our curriculum. We emphasize values such as integrity, compassion, and responsibility, instilling in our students a strong educational foundation to serve them throughout their lives.


God bless,
