Blessed Trinity Catholic High School operates on an A/B block schedule that permits students to take up to eight classes with four classes meeting each day.

Many courses are offered on multiple levels: Academic, Advanced, and Honors/AP. Students are not necessarily placed in the same level in all subject areas. Placement in a particular level is based on the student's aptitude and performance in the various disciplines. While the curriculum is parallel, in that each level of the course has similar goals and objectives, the level of instruction varies by methodology, degree of difficulty and volume of information presented.

• Academic Level courses are designed to meet the needs of students who want a college preparatory curriculum.
• Advanced Level courses are designed to meet the needs of students who want a college preparatory curriculum, who can complete tasks with minimum supervision, and who have an above average level of aptitude and achievement.
• Honors/AP Level courses are designed to meet the needs of students who want an advanced college preparatory curriculum, who are highly motivated, and who have a high level of responsibility, aptitude and achievement. Principles and concepts are explored in greater depth and more independent work is expected of the student. 

Honors and AP courses are weighted. For Honors courses, the grade appearing on the report card and transcript has four additional points added to the actual earned grade. For AP courses, the report card and transcript have an eight-point addition. Therefore, the maximum grade that a student can earn is 100 in an Academic or Advanced level course, 104 in an Honors course, and 108 in an Advanced Placement course. However, no weight can change a failing grade to passing. No weight will be added to a failing grade.
