The school board on Wednesday night approved the retirements, which go into effect at the end of the year.
Superintendent Richard Sniscak called it a "bittersweet" moment.
The teachers' contract gives them until mid-January to notify the district of retirements, which is why so many were up for consideration at once, said Nicole McGalla, the district's director of community relations and development.
The retirees include Ironton Elementary Principal Lynette Smith, who has been with Parkland for 29 years (36 years in total), and Louise Fick, the supervisor of special education, who has been with the district for 19 years (32 years in education).
