More than half a dozen states are considering legislation to offer private school vouchers for students with disabilities.

They are looking to join the ranks of four othersArizona, Florida, Ohio, and Utahthat already offer that school choice option.

Supporters say that such vouchers are an important safety valve for parents when public schools don't offer programs to meet those students' specialized needs.

But opponents warn that parents who take advantage of those vouchers may be giving up procedural protections guaranteed to their children under the federal Individuals with Disabilities Education Act.

They also argue that vouchers for students with disabilities lay the groundwork for universal voucher programs that would drain money from public educationand point to Utah's experience as an example.

In that state, the 2-year-old Carson Smith Special Needs Scholarship entitles students with disabilities to receive up to $6,042 a year for private school tuition. Utah's governor on Feb. 12 signed into law a measure making vouchers available to all students in the state, though the program is expected to face legal challenges.

"The Utah program is enormously significant," said Marc Egan, the director of federal affairs for the National School Boards Association, in Alexandria, Va. "It unmasked the whole push for vouchers. The end goal has always been full-scale private school vouchers for all kids."

Jeanne Allen, the president of the Center for Education Reform, a Washington group that advocates charter schools and other forms of school choice, rejects that claim. The supporters of vouchers are just as diverse in their goals as the supporters of traditional education, she maintained.

"I don't think that most people see this as a camel's nose into the tent," Ms. Allen said.

Varied Proposals
Legislation to offer vouchers for students with disabilities is currently on the table in Georgia, Kentucky, Mississippi, Nevada, Oklahoma, South Carolina, and Texas.

"It's another opportunity for parents to take control of their child's education," said Assemblywoman Valerie E. Weber, the Republican who introduced the measure.

Some states are further along in the process. In Georgia, the Special Needs Scholarship Act passed the Senate in January and is under consideration by the House. Senate President Pro Tem Eric Johnson, one of the sponsors, predicts a close vote for the program, which would offer students a scholarship equal to the cost of the educational program the student would have received in public school.

"There's all these problems, all these myths about vouchers," said Mr. Johnson, a Republican. But he said that lawmakers seem to recognize that students with disabilities "may seriously have unique needs that the regular schools can't meet."

Florida set the precedent for such vouchers with the Florida McKay Scholarship. The 7-year-old program provided an average scholarship amount in 2005-06 of $7,000 that parents of students with disabilities could use to pay tuition at a private school of their choice. About 17,300 students participated in the program during that academic year.

"It's definitely a growing movement. Florida paved the way for us to look at choice in a variety of different ways," said the Center for Education Reform's Ms. Allen. These programs "have become more popular and increasingly accepted by more diverse constituencies," she said.

Matt Warner, the education task force director for the American Legislative Exchange Council, a Washington-based association for conservative state lawmakers, said his group provides model legislation on special-needs vouchers.

"As states have experience with these voucher programs, they'll see that they're not a bogeyman at all," Mr. Warner said. "In fact, these are the great equalizers."

Mr. Egan, however, views such programs as a way of smoothing the path for the acceptance of universal vouchers, which his group, the NSBA, opposes.

"To us, it's more of a political strategy on the part of the voucher supporters to go for these more targeted programs," he said.
