On page 2 (page 8 of the PDF version) of the Student/Parent Handbook it states that the following information can be released to the public:

-student's name

-grade

-school currently or most recently attended

-dates of attendance

-date of graduation

-awards received

-participation in officially recognized activities and sports

Military recruiters and institutions of higher education may also obtain the student's address and telephone number. This is for all students, not just seniors.

Parents or guardians may notify the school in writing if they do not wish that this information be released. I assume that the school will post this information some place accessible.
