Year round schooling is an alternative to the traditional September to June school calendar, replacing the long summer break with shorter, more frequent breaks spread across the year. The idea is straightforward: instead of students going ten to twelve weeks without structured learning in summer, breaks are distributed more evenly so knowledge retention stays higher throughout the year. This article explains how year round schooling works, what the research says about learning retention, and what it means for Canadian families.
The problem with long summer breaks
Traditional school calendars often include a long summer break, typically lasting 8–12 weeks. While this time off provides students with opportunities to rest and engage in non-academic activities, it also results in significant knowledge loss. Research from the Britannica Education Overview suggests that students can lose up to two months of math and reading skills during this period, often referred to as the “summer slide.”
This phenomenon is particularly problematic for students from low-income families, who may lack access to educational resources over the summer. As a result, teachers often spend the first few weeks of the new school year reviewing material from the previous grade—time that could otherwise be spent on new learning. Addressing this inefficiency is one of the key motivations behind year-round school models.
How year round schooling works
Year-round schooling reimagines the traditional academic calendar by breaking the school year into shorter terms with more frequent breaks. One popular model is the 45-15 plan, where students attend school for 45 days and then take a 15-day break. Alternatively, the week-on-week-off approach proposes a cycle of five days of classes followed by a week of rest. This ensures that students and teachers remain refreshed while minimizing the risk of knowledge decay.
The benefits of this schedule include:
- Consistent learning retention by reducing the length of breaks.
- Opportunities for remedial instruction during shorter breaks.
- More balanced workloads for students and educators alike.
Furthermore, this model aligns with the natural rhythm of learning, where regular reinforcement is key to long-term retention. According to Educational Psychology Studies, spaced learning—distributing study over time—leads to better outcomes than cramming information into a short period. Year-round schooling operationalizes this principle on a systemic level.
Year round schooling in Canada – which provinces use it?
Year round schooling is not common in Canada. The vast majority of Canadian schools follow a traditional September to June calendar with a ten to twelve week summer break. A small number of independent and private schools have experimented with modified calendars, but no province has adopted year round schooling at a system-wide level.
This means that for most Canadian families, the question is not whether their child’s school uses a year round calendar – it is how to maintain learning momentum during the long summer break that the traditional calendar creates.
The summer slide is real in the Canadian context. Research consistently shows that students lose ground in mathematics over a long summer, and that the loss compounds across years. Students from lower-income households and those who already have gaps in foundational skills tend to lose more. When September arrives, teachers typically spend the first two to four weeks reviewing material from the previous year: time that comes directly out of new learning.
Practical considerations for families
For families considering a school that does use a modified calendar, the practical questions are slightly different from the research questions.
Childcare logistics change significantly. Year round schools take breaks in September, November, and March rather than concentrating them in summer and Christmas. For working parents, this can be harder to manage than a single long summer break, even if the total number of days off is similar.
Extracurricular activities built around the traditional calendar – summer sports leagues, summer camps, family holidays – need to be rethought. Some families find this disruptive. Others find that shorter, more frequent breaks actually fit family life better than one long summer.
Academic adjustment takes time. Students moving from a traditional to a year round school typically need a term to adjust to the different rhythm, and performance may dip initially before improving.
How to prevent summer learning loss regardless of your school calendar
For Canadian families whose children attend traditional schools, the practical question is not whether to switch to a year round calendar — that is not an option for most families. The question is how to keep learning ticking over during summer without turning the holiday into a second school term.
A few approaches that work:
Short, regular practice sessions are more effective than intensive bursts. Twenty minutes of math three or four times a week across the summer is significantly better for retention than a cramming session in August before school starts.
Keeping the focus on concepts rather than procedures helps. A child who understands why long division works will remember it in September. A child who memorised the steps without understanding them often needs to relearn from scratch.
Structured programmes with a clear curriculum give children a sense of progress rather than just drilling. Think Academy’s summer programmes follow the same spiral advancement model as the term-time curriculum, revisiting concepts at increasing depth rather than simply reviewing what was covered the previous year.
For students preparing for competition math — AMC 8, Waterloo Gauss, Math Kangaroo — summer is also the most efficient time to build preparation, since there is no competition between practice and school homework.

Frequently Asked Questions
Do Canadian schools use year round schooling?
Year round schooling is not widely used in Canada. The large majority of Canadian schools follow a traditional September to June calendar. A small number of independent schools use modified calendars, but no province has introduced year round schooling at a system-wide level.
What is the summer slide?
The summer slide refers to the learning loss that occurs during long school breaks, particularly the summer holiday. Research suggests students can lose up to two months of math progress over a traditional summer break. The effect is larger in mathematics than in reading, and larger for students who already have gaps in foundational skills.
Does year round schooling improve academic performance?
Research on year round schooling shows mixed results overall. The clearest benefit is in reducing learning loss between terms. Studies suggest year round students lose less ground over breaks than students on traditional calendars. However, the overall academic performance difference between year round and traditional schools is modest, and varies significantly depending on the quality of teaching and curriculum rather than the calendar structure alone.
What is the 45-15 school model?
The 45-15 model is one of the most common year round schooling formats. Students attend school for 45 consecutive days, then take a 15-day break. This repeats four times across the year. The total number of school days is the same as a traditional calendar — typically 180 days — but the breaks are distributed more evenly rather than concentrated in summer.
How do I prevent summer learning loss for my child?
Short, regular practice sessions spread across the summer are more effective than intensive review in August. Focus on understanding concepts rather than memorising procedures. Structured programmes with a clear curriculum, like Think Academy’s summer courses, give children a sense of progress and keep foundational skills sharp without turning the holiday into a second school term.
