About this school:


Providing quality education for the last 27 years, St. Peter's ACHS College School is a Catholic (elementary day/residency) school for boys grades JK-8. The school promotes leadership along with traditional and interactive learning, offering a student/staff ratio of 12-1. At our school, students are able to work at their own ability level and speed allowing for a greater success rate. This is a unique and outstanding school for boys who love activity, sports and the outdoors. We put the FUN back into learning.

The Our Kids review of St. Peter's ACHS College School

our takeSt. Peter’s was founded in order to address a very specific kind of learner: active boys. There’s a hockey player in the school logo, though the athletic program is certainly not limited to that, nor is St. Peter’s intended as a hockey school. That program is strong, though the athletics here range in ways that you’d not typically expect in a school of this size. The focus is on physical health, and modelling a physically active lifestyle. Those programs, too, are intended to create a space in which boys are more apt to apply themselves to core academics, and the success of the school for the parents who enroll their children here is based there. It’s an atmosphere in which boys, often, will achieve a higher success in academics than they would in a more traditional educational setting. The school was founded in 1990, and has had a few locations since then, though in 2014 moved into its current facility. Values, too, are promoted, and the curriculum is taught through the lens of Catholic faith. The ideal student is one able to thrive in a very active, challenging, and team-oriented academic environment.

Principal's Message


Peter Thyrring, Headmaster

Since 1990 St. Peter's ACHS College School has helped active and athletic boys get ahead and prepare for a most awesome and challenging future. 

Students here are able to excel at their own level, and pace, through interactive learning and individualized programming. Our school is extremely dedicated to the highest academic standards and stresses effort, responsibility, and self discipline to accomplish maximum success.

Boys learn differently than girls and research confirms that boys thrive in an all boys learning environment. Our innovative approach has brought "FUN" back to learning. We ingrain old school values in our students to forge ahead of the pack. Our school also stresses "A HEALTHY BODY, A HEALTHY MIND". Daily athletics, along with leadership development, are large components at our school. By developing a healthy body, our students build character and experience greater mental and emotional well-being.

As a private school, we are truly unique. With our small class sizes and family atmosphere, knowledge and friendships are made to last a life time.      

After many successful years in the GTA and Haliburton we recently consolidated and relocated our schools to a larger facility in the Windsor/Essex Region. We are now proud to be a part of the Amherstburg community. I invite you and your family to consider our school along with all the benefits it has to offer your son.


Curriculum Traditional

Primary Curriculum: Traditional

What St. Peter's ACHS says: At St. Peter's ACHS we emphasize developing a healthy body and mind through athletics, but academics is paramount. Working at a student's individual pace and academic level allows our students to achieve Ontario Curriculum goals, in full, without worry of being left behind before a concept is grasped, or sitting in a classroom bored waiting for everyone else to catch up.

  • Pedagogies and subject courses:

  • Mathematics Traditional Math

      Traditional Math typically teaches a method or algorithm FIRST, and THEN teaches the applications for the method. Traditional algorithms are emphasized and practiced regularly: repetition and drills are frequently used to ensure foundational mastery in the underlying mathematical procedures. The traditional approach to math views math education as akin to building a logical edifice: each brick depends on the support of the previously laid ones, which represent mastery over a particular procedure or method. Traditional Math begins by giving students a tool, and then challenges students to practice using that tool an applied way, with progressively challenging problems. In this sense Traditional Math aims to establish procedural understanding before conceptual and applied understanding.
      Learn about the different mathematics approaches  

    • What St. Peter's ACHS says: Students work at their own pace throughout the year and receive individual instruction on concepts before putting these concepts to practice. Curriculum expectations are worked through linearly, building on previous knowledge, and students do not move on until a cumulative assessment of skills is completed and passed.

    Early Reading Balanced Literacy

    Writing Equal balance

    Social Studies Core Knowledge

      Usually focused on teaching history and geography at an early age, the core knowledge approach uses story, drama, reading, and discussion to teach about significant people, places, and events. Breadth of content and knowledge is emphasized. The curriculum is often organized according to the underlying logic of the content: history might be taught sequentially, for example (as students move through the grades).

    Foreign Languages Audio-Lingual

      The audio-lingual method of teaching foreign languages emphasizes the use of repetition and a system of immediate reinforcement and feedback. The method makes particular use of oral drills where students are expected to correctly imitate (or intentionally alter) an utterance made by the teacher in the target language. Quizzes and worksheets are also used extensively.

    Computers and Technology Heavy integration

      A major effort is made to integrate the development of digital literacy throughout the curriculum and in everything students do. Digital literacy is understood to be a fundamental skill in the 21st century: it therefore follows, the idea goes, that teachers should find ways to connect every lesson back to technology. Effort is made to ensure the use of technology is meaningful and advances students’ skills beyond what they would otherwise be from using computers outside the classroom.

    What St. Peter's ACHS says: This information is not currently available.

    Mostly value-neutral

    By and large, we teach sex education free of any particular moral or ethical standpoint. We try not to impose any particular values or value systems (such as social, political, or ideological values) on our students when teaching sex and related issues.

    Fairly value-based

    Sex education is sometimes taught from a particular moral or ethical standpoint. Sometimes particular values or value systems (such as social, political, or ideological values) are invoked when teaching sex and related issues.


    This includes a range of positions. A traditional approach might, for example, go as far as emphasizing the nuclear family and complete abstinence from sex before marriage. Alternatively, this approach might simply involve placing less emphasis on sex outside of the context of marriage and more emphasis on abstinence. Or finally, it might just involve focusing less on sex outside of the context of marriage.

    69 % of Our Kids' schools use a traditional approach for sex and health education


    This might mean more emphasis is placed on the importance of such things as social equality, diversity, and choice in sex education.

    Curriculum Pace Student-paced

    • Standard-enriched
    • Accelerated
    • Student-paced

    The main curriculum pace is non-standardized and is HIGHLY responsive to the pacing of individual students, (via differentiated instruction, differentiated assessment, etc). In theory, some students outpace the default/normalized curriculum, while others spend periods "behind schedule" if they need the extra time.

    Flexible pacing:

    Flexible pacing style = offered
    Subject-streaming (tracking)
    Multi-age classrooms as standard
    Ability-grouping (in-class) as common
    Frequent use of cyber-learning (at-their-own-pace)
    Regular guided independent study opportunities
    Differentiated assessment

    What St. Peter's ACHS says about flexible pacing: This information is not currently available.

    Academic Culture Rigorous

    • Rigorous
    • Supportive

    A school with a “rigorous” academic culture places a high value on academic performance, and expects their students to do the same. This does not mean the school is uncaring, unsupportive, or non-responsive -- far from it. A school can have a rigorous academic culture and still provide excellent individual support. It does mean, however, the school places a particular emphasis on performance -- seeking the best students and challenging them to the fullest extent -- relative to a normal baseline. High expectations and standards – and a challenging yet rewarding curriculum – are the common themes here. Keep in mind this classification is more relevant for the older grades: few Kindergarten classrooms, for example, would be called “rigorous”.

    What St. Peter's ACHS says: Students take pride in being academically elite, and are held to the highest standards of the curriculum while in a supportive learning environment. Individualized pace and learning styles are considered to turn struggling students into performing ones and to push gifted students to reach their potential.

    Developmental Priorities Intellectual, Physical

    Primary Developmental Priority: Intellectual
    Academically strong, creative, and critical thinkers, capable of exercising rationality, apprehending truth, and making aesthetic distinctions.

    Secondary Developmental Priority: Physical
    Strong, flexible-bodied, and active individuals, in tune the joys of movement, sport, and wellness.

    What St. Peter's ACHS says: We believe through developing a healthy body, our students build character and experience greater mental and emotional well-being. This allows them to thrive academically, emotionally, and develop important leadership skills.
