I have one child who completed three years at ISSM, and another who is beginning his third year (Pre-K) there this fall. We love this school beyond words. Edith, the director, truly connects with each child as an individual and strives to adapt to their needs. The assistant teachers have also been wonderful, nurturing, and creative. This is a Montessori school where the kids learn to make choices and exercise independence on what they work on. There is structure, but they work with each child's natural inquisitiveness rather than impose a strict plan. I found it to be a wonderful place for my kids, who have different temperaments and interests. Many families over the years have gone out of their way to stick with ISSM through multiple kids, even through changing life circumstances, which really speaks to what a special place it is. This is a single-classroom facility in BAX, but it's a wide open space, and the teachers rotate the materials throughout the week. For physical activity, there is a trampoline, a slide, a Pikler triangle and ramp, which get rotated in and out of the space as the days go on. They also go outside to JJ Byrne some days. The school has a music teacher visit once or twice a week, to sing and encourage the kids to stand up and dance. I got to participate in some of these lessons when everything was closed in 2020, and I could see for myself why the kids love them! The fact that it's a single classroom also means it is mixed-age, which I also found worked wonderfully for my kids. While sharing the classroom with kids of a different age, I found that it gave them a sense of perspective and empathy. In the older kids, they saw role models, and towards the younger kids, and I saw them develop a sense of nurturing that is very sweet. Their relationship to the classroom and their classmates changed every year as they got older. ISSM is a Spanish-immersion school, and I can also attest to the high quality of their instruction in Spanish. They do a great job maintaining the immersive quality while working with kids of various levels of proficiency. If you value a Montessori education, Spanish immersion, or both, you should definitely check out Imagine South Slope Montessori. Amenities: They visit a nearby playground with the kids some mornings. So they do not have private outdoor space, but they go outdoors nonetheless.
