For example, Mr. Johnston has stated that the alternative school he helped establish and where he was a principal “made Colorado history by becoming the first public high school in which 100 percent of seniors were admitted to four-year colleges.”

Interesting, fairly "even handed" look at 'real teachers vs. dress-up teachers' struggle.
