Some say they are concerned that the Arlington school district is searching for a new superintendent for the third time in just five years.
The school board unanimously voted Thursday night to terminate Jerry McCullough.
"I shouldn't second-guess them, but that's a lot of searches," Mayor Robert Cluck said. "But I don't have any way to measure that and whether it's excessive or not because I haven't been in the trenches with them."
"It makes me concerned about my children's education and the direction that Arlington is going," said Marqus Smith, the father of three Arlington students.
Some Arlington Independent School District teachers share his concern.
"There's probably an uncertainty of vision -- which direction is the district going on in certain aspects, whether it be testing or other aspects?" said Trinetta Perez, an AISD teacher, coach and parent.
Even future teachers such as Hillary Marrow, who attends the University of Texas at Arlington, say they fear the uncertainty could trickle down.
"I don't want to have a principal with turnover rate that high," she said.
But not everyone is concerned about the district's superintendent turnover rate.
"They may just be ... looking for the right person," said Janice Doerge, who has several grandchildren in AISD schools. "Sometimes you have someone, and they turn out to be not what you thought they are."
Smith said the problem could be larger.
"Maybe the whole system is flawed," he said. "Maybe ... they're trying to blame the individual person or man, [but] maybe it's the system as a whole."
Doerge and Perez said the superintendent position is a tough job.
"The superintendent's job is the hardest job I can ever imagine," she said. "You can't please everybody all the time. It's a job I wouldn't wish upon anybody."
