Brittnie Pemberton listened attentively as Jim Herrick took her and her mother, Tanya, on a brief tour of San Diego State University on Thursday. Her dream is much closer to reality after she received a promise from the university. The university promised that she would get a full four-year scholarship to the school as long as she met the entrance requirements.

Brittnie, 10, laughed. Her mom cried.

They live at the Salvation Army Door of Hope, a living center for homeless women and their children. Photojournalist Linda Solomon met them in August when she came to the facility and taught boys and girls, ages three-and-a-half to 13, how to take pictures. She gave them all disposable cameras and told them to capture images that reflected their dreams. The children's images - a big house, a church, a playground, a backyard and more - are kept. This is a project called“Pictures of Hope" organized by the Salvation Army

"I wish to go to college, so I took a picture of the sign out in front of San Diego State University," Brittnie said last month. The Fletcher Elementary School fifth-grader was pointing to the Christmas card bearing her photograph.

Adrienne Finley, development director at the Salvation Army, hosted a reception for Solomon, who told Finley about the president of a small university who gave a child the scholarship she dreamed of last year.

Finley called his old friend, Herrick, who serves as the SDSU President. "We have a wonderful opportunity here to make a difference in a little girl's life," Finley said. Soon her mom and Brittnie were face to face with SDSU President Jim Herrick.

"You must be Brittnie," he said, reaching out to shake her hand. She quickly pulled her hands out of the pockets of the new SDSU sweatshirt she had been given that morning.

They sat down at a table in his office and talked about college, about science, about her love of math and his hope that she and other girls wouldn't lose interest in those subjects, as happens to many girls as they grow older.

Then they talked about how much discipline she would need over the next eight years to make her dream come true. Both signed the paper outlining their agreement to the terms of the scholarship. Back outside on the sunny campus, Brittnie admitted she's tempted sometimes not to do her homework. "But not anymore," she said.
