Leaders of the nation's Hispanic community yesterday called on the presidential candidates of both parties to pledge to name Hispanics to the Cabinet and Supreme Court, oppose the English-only movement, press for changes in the Simpson-Rodino Immigration Act, and increase spending on education, housing and health programs.

The list was put forward in the National Hispanic Agenda '88, a document drafted over the past several months and released yesterday by a bipartisan group of more than 100 Hispanic elected officials and community leaders from 20 states.

"We have been given less attention {in the presidential election} than our size and growth potential warrants," said Henry Cisneros, mayor of San Antonio and chairman of the task force that prepared the agenda.

There are 18.8 million Hispanics on the mainland and 3.3 million in Puerto Rico. They are the fastest growing minority group in the country. Since 1980, the U.S. Hispanic population has increased by 30 percent, compared with 6 percent for the non-Hispanic population.

The agenda is the first attempt to craft a single policy document for a varied community composed mainly of Mexican Americans, Cuban Americans, Puerto Ricans and Central Americans. It is being delivered to the candidates at a time when "special interest" pleading by any group is looked upon warily, especially by Democrats, who remember how Walter F. Mondale was stigmatized because he supposedly bowed to certain special interests in the 1984 presidential campaign.

"What's wrong with being a special interest?" asked Denver Mayor Federico Penåa. "We are going to become a significant political force in the country and this agenda will help us speak with one voice."

Leaders of the task force said yesterday they plan to conduct forums with the Republican and Democratic candidates later this year, but noted that they did not plan, as a group, to endorse candidates.

The agenda reflected the concerns of a population whose poverty rate is nearly three times that of non-Hispanics.

It called for a National Early Childhood Education Initiative that would provide educational services to all 4- and 5-year-olds living below the poverty line; expanded dropout prevention and literacy programs, an expansion of small business programs, and an increase in funding for low-income housing.

It reiterated longstanding calls for Hispanic appointments to the Supreme Court and the Cabinet. At a meeting of the League of United Latin American Citizens earlier this year, several Democratic presidential candidates -- including Massachusetts Gov. Michael S. Dukakis and former Arizona governor Bruce Babbitt -- promised to appoint a Hispanic to the Cabinet, and Jesse L. Jackson said he would appoint a Hispanic to the Supreme Court.

On immigration policy, the task force report called for a phasing out of employer sanctions and an easing of rules regarding reunification of families.

On language policy, the report said that while "there is no question that English is the de facto language of the United States," English-only laws deprive non-English-speaking citizens of such basic rights as voting.
