Melissa Fanshaw, principal of Rodgers Forge Elementary, said the formula for her school's success is simple.
"The good instruction that happens in our classrooms every single day is key," Fanshaw said.
The Towson school was the only one in Baltimore County to have 100 percent passage rates in all subgroups on the 2012 Maryland State Assessment.
Bill Reinhard, a spokesman for the Maryland Department of Education, said several schools statewide have achieved this same honor but the department has not yet compiled a list of them.
According to Maryland Department of Education data, Rodgers Forge had at least a 94 percent in all subgroups in 2011.
"Historically, the school's scores have always been high," Fanshaw said. "But scoring 100 in all subgroups...it's just an amazing accomplishment."
Schools Superintendent S. Dallas Dance praised Fanshaw and her staff at a Tuesday night Board of Education meeting.
"I want to see what they're doing over there that we can highlight in other BCPS schools," Dance said.
Fanshaw hopes Dance will follow through on his intention to visit Rodgers Forge.
"I was so excited to get the shout-out and I look forward to meeting him, and welcome the opportunity to have him come and visit our classes," Fanshaw said.
She credited the school's committed teachers and supportive parents for the students' success.
"We certainly will do something to celebrate," Fanshaw said. "Plans are in the works."
