President Bush's plan to expand the No Child Left Behind Act's demands at the high school level--a top priority of his second-term domestic agenda--is "not likely" to move forward on Capitol Hill in 2005, a senior House Republican on education issues predicted. Representative Michael N. Castle, R-Delaware, the chairman of the House Education Reform Subcommittee, speaking at a Feb. 9, 2005, forum in Washington sponsored by the Business Roundtable, noted that some conservatives in Congress are dissatisfied with the No Child Left Behind Act and will have little appetite for expanding its mandates, and that more liberal members are frustrated with current funding levels under the law. For his part, Mr. Castle said he is generally supportive of the president's plans for high schools, but would oppose paying for those by shifting money away from existing vocational and technical education spending, as President Bush proposed in his fiscal 2006 budget. Representative Castle's remarks are one of the clearest political signals yet that the president may have a tough time persuading Congress to go along with his plans for expanded testing and accountability requirements in high school.
