State education officials say schools around Colorado may have to foot an estimated $1.8 million bill for new English-language proficiency tests required by federal law.
The No Child Left Behind Act requires school districts to assess the progress of non-native English speakers, but it's unclear who has to pay for the testing.
The new Colorado English Language Assessment replaces three different tests that districts were allowed to choose from because the federal law says that by 2006, all states have to use one common test.
Aurora Public Schools spokeswoman Georgia Duran says the district has about 11,000 non-native English speakers. She says Aurora school officials expected the state to pick up the cost.
But Karen Stroup of the state Education Department says districts will have to cover the costs of testing English-language learners the same way they always have -- using state funds and federal grants.
