Today was the first day of school for most -- but not all -- Tri-City students, and two districts already were reporting student enrollment increases.
Pasco welcomed kids in grades K-5, sixth and ninth back to school Tuesday. The other students will join them today.
On the first day, Pasco had 7,496 elementary school students, 1,123 sixth-graders and about 857 high school freshmen, said Leslee Caul, a district spokeswoman.
Elementary schools showed an increase of 332 students -- or 5 percent -- over first-day figures for 2010. This figure does not yet include new kindergartners at Captain Gray Early Learning Center.
The Richland School District had everyone in school Tuesday.
Its elementary schools had 4,804 students on the first day. The three middle schools housed 2,557 students Tuesday, and 3,667 high schoolers showed up for class, said Steve Aagaard, a district spokesman.
Overall, Richland had 11,435 students on opening day, which is a 2.5 percent increase over last year's first day at school.
Kennewick schools were open for all elementary and middle schoolers Tuesday, but only freshmen attended its high schools on the first day.
It did not yet have enrollment numbers available.
