No work is considered done until it is error free, so students spend time each morning getting yesterdays work letter perfect. When they finish a piece of work, it goes into a folder, so students have a record of what they have accomplished, and every month they take this home to show their parents. The Calvert program has been in existence since 1905. That means that a lot of collective wisdom has gone into perfecting it. Many reforms are adopted without the time or resources to make them work.
Teachers get a couple of workshops at the beginning and a brief follow-up later in the year.
Basically, they are on their own. In contrast, Calverts plan for carrying out its program is as well thought-out as the program itself. When the Calvert program came to Barclay, it was implemented first in grades K-1 and then in one grade per year. So most teachers had a chance to see the program in action before deciding whether they wanted to participate. As a result, the teachers who have chosen to stay are nearly all committed to making the program a success.
