Last week's grants, announced by the D.C. Commission on the Arts and the Humanities, are not the last word on the subject. Many of the grants to the most prominent arts organizations in town were "recognition" grants of $1,000, a token amount given simply to put the commission on record as supporting such enterprises as the Washington Opera and the Folger Library. But proposals in the 1983 budget, which comes before the City Council this week, call for a massive escalation which would increase the commission's funding from about $800,000 to about $1.5 million.

This budget, if approved, will provide for grants of $100,000 each to Lansburgh's and the Ellington School and grants of $45,000 each to eight major cultural institutions in the city: Arena Stage, the Corcoran Gallery, the Capital Children's Museum, the Washington Opera, the National Symphony, the Washington Performing Arts Society, the Washington Ballet and The Rep Inc. In the case of WPAS, which is a booking rather than a performing organization, the funds are to be used for concerts in the schools or to showcase artists from the District of Columbia.

Still missing among grant recipients is the financially troubled Washington Civic Opera.
