Next fall, Ilan will be enrolled in The Shefa School, a new Jewish day school created specifically for students with language-based learning disabilities. Shefa (which means “abundance” in Hebrew) will open its doors in September, in space rented from Lincoln Square Synagogue on Manhattan’s Upper West Side. At the moment the school is just empty white rooms, with small, colorful plastic chairs stacked under a drop cloth on the synagogue’s second floor. But Ilana Ruskay-Kidd, the founder and head of Shefa, is excited as she shows a visitor the large balcony that looks over traffic rushing up Amsterdam Avenue and will soon host playground equipment and the congregation’s sukkah.
