Since 1983 Yale has held a series of meetings to disseminate the Teachers Institute approach and to collaborate with school and university colleagues from around the United States.
At news conferences in 1978, 1982, and 1986 the Yale-New Haven Teachers Institute announced the awarding of grants by the National Endowment for the Humanities.
In 1986, Institute Director James R. Vivian testified before the United States Senate Subcommittee on Education, Arts and Humanities at the invitation of Senator Dale Bumpers (R-AK) in support of “A Bill to Provide a National Program for Improving the Quality of Instruction in the Humanities in Public and Private Elementary Schools” that had been introduced by Senator Bumpers. Vivian offered testimony at hearings also in 1985, 1990, 1991, and 1992.
At the completion of endowment challenge grants awarded in 1990 by the DeWitt Wallace-Reader's Digest Fund and in 1991 by the National Endowment for the Humanities, the Yale-New Haven Teachers Institute became the first permanently endowed program of its type.
