     Amiya Olden could have been a poster child for a reading crisis that affects nearly 2

million Michigan residents older than 16:They read below a sixthgrade level,which makes

it difficult to find jobs and to improve their lives.Among them,Amiya is one.

     Amiya Olden remembers well the day she graduated from Denby High School.She

handed her diploma to her mother,who read it to her."Then when someone asked me to

read it,I could remember the things she read,and I knew what I had to say," recalled

Amiya Olden."When we would go out to restaurants with my aunts,and that's when I

really would get upset,I would see words on the menu but I couldn't read!"

     But don't feel sorry for her.She changed her life by reaching a point where she'd read

enough.Two summers ago,she took charge of her life when she walked into ProLiteracy

Detroit to improve her reading.Nineteen months ago,she was reading at a secondgrade

level；now at a fifthgrade level.

     Olden now splits her days between her classes at ProLiteracy and the library,where

she checks out books and reads them.She says she hopes her improved reading skills

will help her find a good job.

And she has advice for others,who have trouble reading.

     "Don't give up on it," she said."Even though it can be challenging and you might get

frustrated sometimes,practice does help.If you really want to be able to go somewhere,

go out to a restaurant and you have to read signs and things like that,you want to know

what you want to eat and where you want to go...If you want to succeed in life and grow,

you have to read.More importantly,you have to feel confident that you can."
