MADISON, Wis. — Republican state lawmakers are making another push to extend taxpayer subsidies to help students with special needs attend private schools.

The idea was removed from Gov. Scott Walker's budget last year in the face of strong opposition from disability rights groups and others. But four Republican lawmakers scheduled a news conference Tuesday to release their latest proposal.

Families of students with special needs are speaking out about the idea, saying private schools aren't accountable because they aren't required to provide the same services that public schools do under federal law.

Wisconsin Education Association Council, the statewide public school teachers union, also opposes special needs vouchers. Its president Betsy Kippers says lawmakers should invest in public education rather than vouchers.
