Central Bucks School District suspended Natalie Munroe on Wednesday after parents complained about the postings, which called students "out of control" and "disengaged, lazy whiners."
District spokeswoman Carol Counihan tells the Bucks County Courier Times that Munroe acknowledged writing the posts when confronted. She was immediately suspended with pay and the blog was quickly taken down.
Superintendent Robert Laws says the postings should result in termination but the district is still investigating.
A phone listing for Munroe could not immediately be located Thursday.
