DENVER — Desiree Conklin says her son is dyslexic and, as a result, a victim of some “teacher bullying.”

Her 14-year-old son attended Grant Ranch School in Denver, and as he was going through 8th grade “continuation” ceremonies last week, he noticed the word “completed” had been crossed out and replaced with “attended” on his certificate

His mother was furious, “That was the last straw!”  Conklin says the word was crossed out, even after school educators were instructed not to do so.

She played a voice mail for FOX31 Denver that she says is from the school district, apologizing.

Conklin says her son has been “bullied” by some of his teachers over the past four years for “not being at grade level.”

The Denver Public School District released the following statement:

“We are extremely disappointed and disheartened that this happened, and we have apologized directly to the students and their families. The school’s principal gave explicit instructions as to how the ceremony was going to proceed and directed the staff that all students be able to participate in the continuation ceremony and be given certificates. DPS is currently investigating this matter in order to determine why the principal’s directions were not followed and whether further action is necessary. Regardless of the outcome of the investigation, the children should not have been hurt in this way.”
