     American kids are talking more tests than ever before, and they're stressed out. Is help on the way? Just

the sight of a test makes some kids sweat. For others, it is a blank answer sheet. Then there are the frightening

words, "Take out your Number 2 pencil." All three fill 10-year-old Chelsea Logo with fear. "I start to tap my

pencil on the desk," says the fifth grader, "Then I feel the butterflies in my stomach."

     Chelsea is not alone. In a recent survey, more than 70% of kids aged 9 to 13 said they worry about tests.

It's no wonder. Across the United States, public schools give more than 250 million standardized tests each

year.

     Why do kids have to take so many tests? The No Child Left Behind (NCLB) law requires that students in

grades 3 through 8 be tested each year. The law's goal is for all students to be at grade level by 2014. Students

must pass the tests and meet other requirements or their schools may be shut down.

     US Secretary of Education Arne Duncan wants to change NCLB. But that doesn't mean he favors getting

rid of tests. Duncan believes tests should be used mainly to evaluate kids' strengths and weaknesses. Tests,

Duncan says, should not be used to punish kids or their schools for failure. "The goal is to focus on great

teaching and learning," Duncan said.

     Under NCLB, each state sets its own standards for students to meet. The result, Duncan says, is that states

are making the tests easier. To fix this problem, 48 states are now working together to create common

standards. "I want to set a high bar for kids," Duncan says, "so they'll be in great shape to achieve their dreams."

     Like them or not, tests are here to stay. So how can you handle test stress? Schools are teaching students

to relax through deep breathing and stretching. In Oakland, California, Principal Zarina Ahmad of Piedmont

Avenue Elementary leads her students in a cheer to get them excited about learning.
