By late July, many parents start to notice it. The math facts that were automatic in May now take a little longer to recall. The book that would have flown by during the school year sits half read on the nightstand. Educators call this the summer slide, and it is one of the most studied patterns in K-8 education.
Summer Slide: What the Research Actually Shows
The summer slide losses are bigger than most families realize. Research indicates that a large majority of elementary students lose ground in math over the summer months, and well over half lose reading skills during the same stretch. One large-scale study following more than 18 million students found that this loss compounds year over year, so a child who slides every summer can fall meaningfully behind by the time they reach upper elementary school. Math tends to take the bigger hit, since reading habits are easier to keep up casually while math skills usually need deliberate practice.
Why Small Class Sizes Make the Difference
This is exactly where school choice starts to matter. In a classroom of 25 or 30 students, a teacher returning in the fall has to spend weeks figuring out who slid and by how much before real instruction can resume. At Escuela de Guadalupe, our low student-to-teacher ratio means teachers already know each child’s strengths coming into the year, and they can identify and close summer slide gaps in days, not weeks. It is one of the reasons families searching for an elementary school near me in Denver ask us about class size before almost anything else. Small classes are not a nice extra. They are what makes it possible to actually catch a slide instead of just accepting it.
The Dual-Language Edge Over Summer
As a dual-language school, we also see something else in our students. Kids who are actively building two languages tend to stay more cognitively engaged over the summer, especially when families keep both languages active at home. Reading a familiar story in Spanish one night and English the next is not just language practice, it draws on the same kind of mental flexibility that shows up in problem solving and pattern recognition. Research on dual-language immersion consistently links bilingual learning to stronger executive function and academic performance overall, and that foundation does not disappear just because school is out. It is one of the quieter advantages of a dual-language school that families do not always expect when they enroll.
Simple Ways to Avoid Summer Slide
Families do not need a formal curriculum to fight the slide. A few consistent habits go a long way:
- Read for 20 minutes a day, alternating between English and Spanish books when possible
- Make a weekly trip to the library part of the routine
- Practice math through everyday moments like cooking, shopping, or counting change
- Keep a summer journal, even a few sentences a day, in either language
- Save screens for after active time outside, and choose educational apps over passive video when possible
What This Means When You Are Choosing a School
Summer slide is really a proxy for a bigger question every family should ask when comparing schools: what happens when a child falls behind, whether it is over the summer or during a hard unit in October? At a Catholic school built around small classes and individual attention, gaps get caught early because teachers are watching for them, not because a program gets bolted on after the fact. That is the difference between a school that reacts to learning loss and one that is built to prevent it. Families researching the best private school in Denver should ask not just about test scores, but about what a typical September actually looks like.
