Cherry Creek School District Superintendent Harry Bull was named 2017 Colorado Superintendent of the Year on Tuesday.

Bull has led the nearly 55,000-student district for about three years. He has worked in various positions in the same district for 33 years, according to a news release.

“Harry Bull is an outstanding district leader and held in very high regard by his peers across the state,” said Lisa Escárcega in a statement. Escarcega is executive director for the Colorado Association of School Executives, the organization that gave Bull the award. “He is tireless in his advocacy for students and public education, and one of the most effective voices at the state level when it comes to making the case for adequate school funding.”

In his time as superintendent, Bull has been vocal in his support for a change in the way school districts are funded and was also an outspoken critic of the state’s move to abandon the ACT college preparation exam in favor of the SAT.

Under his leadership, the Cherry Creek district recently has been recognized by the state for their work with English language learners.

Bull will now go on to represent Colorado in a national competition for superintendent of the year.

Correction: An earlier version of this story misidentified how many years Harry Bull had worked in the district in other positions.
