I want to know the answer to the following question:
Who said Oklahoma's pre-K program is the best in the US?
All the background I'm provided with is that "The state is among the best in pre-kindergarten education, and the National Institute for Early Education Research rated it first in the United States with regard to standards, quality, and access to pre-kindergarten education in 2004, calling it a model for early childhood schooling.". Is that enough to answer the question?
