Our two organizations – Rosov Consulting and Middlebury College – have been involved in studying an initiative that is at a point of inflection, on the brink of transitioning from start-up to scale. We have had the opportunity to document and evaluate, from the time of its birth – really, since its conception – the Areivim Hebrew at Camp Initiative. With the initiative moving to a second stage of development, developing a co-brand with the Foundation for Jewish Camp, this a timely moment to share some of what we have learned. The goal of the Hebrew at Camp Initiative is to create a movement of Hebrew immersive and partially-immersive Jewish day camp programs where pre- and elementary-school-age children can experience, learn and enjoy modern spoken Hebrew utilizing the Proficiency Approach, a gold standard in language education. The concept is this: young children spend their summer at Jewish day camp; their ability to communicate in Hebrew develops dramatically, they develop a positive connection to Israel, and they have as much fun as their fellow-campers.
