The start of the new school year today in St. Paul marks the opening of three Transitional Learning Centers. District officials created the centers in response to the latest wave of Hmong immigrants moving to the city. Como Park, Hayden Heights and Phalen Lake will serve up to 125 students each in the short-term program. But the district still doesn't doesn't know how many kids will show up. Superintendent Pat Harvey says some of the students who lived in a Thailand refugee camp have little formal education. She says they need a program that provides basic information.
