A parade of alumni will precede the varsity football game on Sept. 29 at the Rocklin High School Homecoming parade and football game.
Each graduating class will carry a banner announcing the year they graduated and the alumni will walk behind the banner.
"We've never done anything like this before," assistant principal Mark Douglas said.
Douglas said he is hoping for a big turnout.
Rocklin High School has graduated 3746 students since its first graduating class in 1997.
The number of graduating seniors has steadily increased from the first graduating class in 1997 of 240 students and last year, Rocklin High School graduated 528 students.
"We've got such a great following in the community, we stand to have a significant amount of kids show up," Douglas said.
Alumni who wish to attend the parade and football game do not need to contact the High School beforehand, all they need to do is show up to the game and check in at the gate, Douglas said.
Mark Douglas said he expects this year's seniors to be the biggest graduating class since it was the last class before Whitney High School opened up.
Alumni are asked to arrive in the stadium by 6:30 p.m. to be ready for the parade time.
Alumni arriving by this time will receive a special entry price of $5. After 6:30 p.m., regular ticket prices apply.
Another highlight of the ceremonies will be the game ball, which will be handed down by RHS football alumni representing each graduating year and presented to Head Coach Greg Benzel.
Event organizers said they have prepared for an excess of people with overflow parking and areas so that they don't have a repeat of a few years ago when more than 8000 people showed up for the homecoming game.
The homecoming parade with floats and royalty will take place at half time.
Regular admission for adults is $6 and $4 for students.
