DIXFIELD — Dirigo Middle School students will be honored at Hadlock Field in Portland on Thursday night for being the only school in the state where every student completed a reading challenge from the Sea Dogs and Maine’s public university system.

“I’m thrilled that a small school in Western Maine will be on the field,” Principal Celena Ranger said.

All 220 sixth-, seventh and eighth-graders completed Slugger’s 2012 Reading Challenge. That means every child read at least five books beyond what is required in their classes.

Caribou Middle School came in second with 69 percent of students meeting the challenge, and Canal School in Westbrook came in third with a 66 percent completion rate.

More than 80 schools throughout the state competed in the challenge, according to a news release issued by the Portland Sea Dogs.

For coming in first, Ranger said the school will receive $1,000 to be used for the purchase of more books, perhaps a party, or some other purpose for the students.

Abby Waleik’s art club at the middle school is making posters and banners that will be used by the students at the game. Anyone who watches Thursday’s game will know when the Dirigo students go onto the field. They’ll be carrying “Cougars” and “Dirigo Middle School” posters.

“I’m really proud of the students and the teachers. The teachers did an amazing job of monitoring the student reading,” Ranger said. He is one of about 20 chaperons who will travel with the students in four buses Thursday.

Each of the youngsters also received free tickets to the game, which Ranger said may be pitched by Red Sox player, Daisuke Matsuzaka, who is just coming off the injury list.

Sixth-grader Cooper Chiasson, of Dixfield, said he looks forward to the event.

“It will be fun hanging out with my friends. I like baseball,” he said.

Sixth-graders Natalee Maurais, of Carthage, and Jenni Prue, of Peru, are also excited about the event.

“It will be fun,” Natalee said.

The Sea Dogs play the Trenton, New Jersey, team on Thursday.
