Do Maryland's citizens want to make this Free State, America's best? Should we be at the vanguard of scientific accomplishment and technical advancement, reinvigorating our universities and providing an attractive environment for modern industry?

The establishment of a Maryland High School for Science and Mathematics will assist in all this. Gov. William Schaefer announced Aug. 1, during the campaign season, that he would revive the idea in the General Assembly next year. In 1986, he also pledged to seek the establishment of such a school.

I strongly urge the governor to place this school at the top of his list of innovative projects to go before the legislature. The success of the Baltimore School for Arts, on whose task force I had the opportunity to serve, gives us the necessary encouragement.

The rejection of initiatives for property tax caps, the great public concern for education and the reelection of Gov. Schaefer by a substantial majority all indicate Marylanders' willingness to pay for the right objectives within fiscal constraints. They also give a mandate that the state leadership should deliver progress in the most cost-effective manner.

Congress recently passed a bill pushed by President Bush ''to establish a network of regional centers to bring state-of-the-art science and math curricula to the nation's elementary and secondary schools.'' The legislation's objective is to make U.S. students first in the world in math and science by the year 2000.

Maryland should move ahead with the establishment of the science and math school, which would help get the state selected for such a regional center. As for funding, federal, state, foundation, business and private contributions should come together. Marylanders should all get behind this project, which is so vital to our country's future. Latest estimates are that at the current rate of college majors, the United States will be unable to fill 1 million jobs in the engineering and science fields by 2003.
