Presidential daughter Jenna Bush has agreed to take a job as a teaching assistant at the Harlem Day Charter school, sources said yesterday.

"I'm going to teach fourth grade," Jenna told students at an Alabama elementary school, which she visited with First Lady Laura Bush.

Harlem Day Chairman Benjamin Lambert said only, "We have nothing to confirm about Ms. Bush's involvement in Harlem Day at this time."

But other sources said the school has offered her a teaching aide position, and she has accepted — starting in September.

Jenna, 22, who just graduated from the University of Texas, will be an aide until she earns credentials to become a teacher.

Jenna's mom, a former school librarian, yesterday offered her daughter some advice about teaching.

"Remember to treat every child with respect," Mrs. Bush. "That's what our children deserve."
