LOS ALTOS, Calif.  “Can we take a look at your backpack?”

Ana Homayoun repeats that question countless times a day. No, she does not screen airline passengers or work security at a basketball arena.

Ms. Homayoun is a tutor. She helps teenagers with subjects like math and science, but she particularly specializes in teaching boys how to become more organized.

One afternoon in her cozy office suite in this affluent suburb south of San Francisco, she asked John Ferrari, 14, to go through a two-inch stack of papers he pulled from his backpack. He sorted through the papers, placing them in separate piles  writing, spelling, vocabulary, tests  to bring order to his loose-leaf binder.

“Oh, here’s my class schedule, what a relief,” said John, an eighth grader.

A moment later, he stumbled across something even more valuable. “I have to turn this in tomorrow,” John said. “It’s the name I want on my diploma.”
