(AP) — A Kansas legislator wants the state to count and report the number of undocumented children in public schools.

Rep. Allan Rothlisberg, a Republican from Grandview Plaza, on Tuesday introduced a bill that he says would help determine how much taxpayer money is spent to educate children who are in the country illegally.

The bill would require a school board to ask for proof of that a child is in the country legally when a child enrolls for the first time in a public school. The proof would be a birth certificate, Social Security card or other document.

The state would publish a record of the number of children who didn’t provide the proof, and the average per pupil school finance cost.
