According to Chalkbeat Colorado, Denver is set to strip 47 teachers of their tenure because they received two consecutive ineffective ratings.

The state law passed in 2010 called S. 191 requires that teachers be evaluated annually, with student scores counting for 50% of the teachers’ ratings. The law was written by State Senator Michael Johnston, who spent two years as a Teach for America recruit. Johnston predicted that his law would cause every teacher, every principal, and every school in Colorado to be “great.” There is no evidence that it has had that effect.

DPS did not provide a list of the schools at which the 47 teachers set to lose tenure taught. But the district did provide some information about the teachers and their students:

— Twenty-eight of the 47 teachers set to lose tenure — or 60 percent — have more than 15 years of experience. Ten of those teachers — 21 percent — have 20 years or more of experience.
Overall, about 33 percent of non-probationary DPS teachers have more than 15 years experience, and about 14 percent have more than twenty years of experience.

— The majority of the 47 teachers — 26 of them — are white. Another 14 are Latino, four are African-American, two are multi-racial and one is Asian.
About three-quarters of all DPS teachers — probationary and non-probationary — are white.

— Thirty-one of the 47 teachers set to lose tenure — or 66 percent — teach in “green” or “blue” schools, the two highest ratings on Denver’s color-coded School Performance Framework. Only three — or 6 percent — teach in “red” schools, the lowest rating.

About 60 percent of all DPS schools are “green” or “blue,” while 14 percent are “red.”

— Thirty-eight of the 47 teachers — or 81 percent — teach at schools where more than half of the students qualify for federally subsidized lunches, an indicator of poverty….

Pam Shamburg, executive director of the Denver Classroom Teachers Association, said the union has long been concerned about this provision of Senate Bill 191 because teachers who are demoted to probationary status lose their due process rights.

She’s also worried it will lead to higher teacher turnover. Ten of the 47 DPS teachers set to lose non-probationary status have submitted notices of resignation or retirement, officials said, though nine of them did so before learning they would lose tenure.

“This happening to 47 teachers has a much bigger impact,” Shamburg said. “There will be hundreds of teachers who know about this. They’ll say if they can do that to (that teacher), they can do that to me.”
