(CNN) An Indiana school superintendent has resigned after being accused of pretending a sick student was her son so he could get medical treatment, CNN affiliate WXIN reported.

Casey Smitherman, the superintendent of Elwood Community Schools, was charged January 23 with official misconduct, insurance fraud, insurance application fraud and identity deception. She officially resigned Friday.

In a statement to the affiliate, she said:

"I have dedicated my entire professional career to children and ensuring they have the best possible chance of success. My record of accomplishments clearly shows I have been successful in doing that. Unfortunately, my recent lapse in judgment has brought negative attention to the community and myself. I am very embarrassed for that, and I apologize to the board, the community and the teachers and students of Elwood Community Schools.

"I sincerely hope this single lapse in judgment does not tarnish all of the good work I've done for students over the span of my career. As most educators will attest, the board, community, teachers and students need to be in alignment for a school system to achieve its goals. I do not feel that alignment exists at this time nor could exist in the near future and therefore, effective 02/01/2019, I am resigning from my position as the Superintendent of Elwood Community Schools. I am confident the board will take the necessary steps to ensure the school system works through this period of change in the best possible way."
