With an assist from Marriott Corp., Domino's Pizza will soon be delivering lunch to students in hundreds of public elementary and high school cafeterias around the country.

Bethesda-based Marriott said yesterday that it had signed an agreement with Domino's under which the two companies will market Domino's pizzas in school cafeterias run by Marriott's food service operation.

The agreement -- apparently the first of its kind in the fast-food industry -- calls for local Domino's franchises to cook and deliver the pizzas to the schools, where cafeteria workers will serve them as part of the regular lunch program.

Marriott will collect a commission on each pizza sold and Domino's franchisees will benefit from the increased sales the deal would generate. Domino's pizza will be distinguished from other pizzas now served with signs placed within the cafeterias.

Marriott now serves more than 120 million meals a year to school-age children under various contracts it has with 200 school systems in 20 states. Domino's will also be allowed under the deal with Marriott to deliver pizzas to college dorms and allow students to charge the cost against their meal tickets.

But some health and education advocates, concerned about commercial inroads on school lunch programs, are finding the plan hard to swallow.

Businesses that market products in public schools have come under attack in recent years from those concerned about the commercialization of education.

Some educators have been critical of ventures like Whittle Communications's Channel One, an advertiser-supported TV network that was launched in classrooms around the country last year.

Yesterday, a spokeswoman for the National Education Association said the Marriott-Domino's deal runs afoul of an NEA resolution advocating that school lunch programs "be supported by public funds" and not run as commercial, for-profit ventures.

A representative of the American School Food Service Association, which represents public-school cafeteria workers, said the organization had "concerns" about ventures similar to the Domino's plan, although it has taken no position on the issue.

Ed Cooney, the deputy director of the Food Research and Action Center, a nonprofit group that lobbies on behalf of nutrition programs for children, said the Marriott-Domino's deal "raises a red flag for nutrition advocates. ... I am not anti-business, but I do think you have to ask whether {Marriott and Domino's} are placing the profit motive above nutrition."

A Marriott spokeswoman said Domino's pizzas meet nutrition guidelines for school lunch programs.

"From our perspective, {brand name food} is something people like," she said.
