The hourlong ceremony was held at Martinsburg High School. It was organized by Berkeley County Business Education Partnership Inc.
Other awards included banners given to employees of three schools - Gerrardstown Elementary, Inwood Primary and Rosemont Elementary - that were named West Virginia Exemplary Schools for 2003-04.
Numerous students also were recognized for a variety of feats, as were school volunteers and service personnel.
Marchese, a first-grade teacher at Gerrardstown Elementary, was required to organize four portfolios based on her classroom work and take assessment tests to become certified.
She estimated she put around 100 hours of work into the effort.
And an effort it is, said Berkeley County Schools Superintendent Manny Arvon.
About 1 percent of the country's teachers are nationally certified, he said.
"Most of the folks who enter the program do not finish because it's so very difficult," he said.
Marchese said undergoing the process enabled her to ensure her teaching lessons did not become rote.
"It's a good process to go through to learn new things," she said, adding that it caused her to implement more group work and inquiry-based activities into her lessons.
Marchese, a Shepherd College graduate, has been teaching at Gerrardstown Elementary for 14 years.
Long, the other nationally certified teacher recognized at the banquet, is a teacher at Mill Creek Intermediate School in Inwood, W.Va.
