Inderkum High School opened in 2004 with Ron Zimbalist as the principal and Darrin Slojkowski as the assistant principal. A few teachers from the first year remain. Its name comes from Frank Inderkum, a dairy farmer who owned the land the school is on. The mascot is a Tiger. School colors are blue and gold. When it was first opened, many students switched from their rival school, Natomas High School, into Inderkum. As the first years went by, Inderkum’s non-charter feeder middle schools are Natomas Middle and Heron K–8. Students from Westlake Charter, Natomas Charter, Leroy Greene Academy, and Natomas Pacific Pathways Prep also feed into Inderkum. A new non-charter school, Paso Verde K-8 will send its first group of students to Inderkum for the 2021–22 school year. The first principal of Inderkum High School was Ron Zimbalist, former Natomas Middle School principal who was principal from 2004 to 2005. From 2005–2007, Ben Flores was the principal. From 2007-2010 the principal was Leslie Sargent. From 2010–2013, George Tapanes, former principal at Fortuna Union High School served as principal. From 2013–2015, Heather Garcia was the assistant superintendent in charge of Inderkum. Since 2015, Dan Motherspaw, who has been at the school since 2005 has served as principal.
Academics
Inderkum houses the culminating International Baccalaureate Diploma Programme since 2012. The first class graduated in 2016. It is one of several high schools in the Sacramento area to offer this rigorous academic program. Students can either complete the full diploma by taking a certain battery of classes or pick and choose certain classes to take. The Middle Years Programme is something that all freshman and sophomores participate in at Inderkum in addition to participating in their middle school years at Natomas Middle School. Students who attend H. Allen Hight and Paso Verde will also participate in the primary years program during their elementary years. Natomas has the first TK–12 IB continuum in the entire Sacramento area. The CaliforniaEarly College Academy started in the 2013/2014 school year. It is an opportunity for Inderkum students to take classes in 9th grade and 10th grade that prepare them to take classes at American River College in certain academic subjects during 11th and 12th grade. During the first five years, cohort sizes were 70 students per year. Beginning with the 2018–19 school year, cohort sizes are now 140 students.
Campus
In the July 30, 2013 issue of Best Education Degrees, there was an article entitled "The 30 Most Amazing High School Campuses In The World.” Inderkum was placed #1 because of its buildings being highly energy efficient and uses electricity-generating photovoltaic panels, a geothermal ground loop system, low-velocity cooling displacement and radiant slab heating. In 2008, the football stadium and track, officially known as Dave Tooker Stadium opened. Mr. Tooker was the superintendent of Natomas Unified when Inderkum opened. It is colloquially referred to the Home of the Tigers. During the summer of 2019, the stadium received a new all-weather field and an all new weather track. On January 9, 2010, the 23,000 square feet library right next to campus. It is a joint partnership between the Natomas Unified School District, the Los Rios Community College District, and the Sacramento County Public Library system. It is available for use during open library hours plus reserved at times with the school librarian. The roof of the library is shaped like an open book.
Athletics
During the second semester of 2008, Inderkum began the construction of a new $2.4 million turf football field and all-weather track for multiple uses, such as football, track, cross country, etc. The construction has since been completed, and is for private use. Inderkum participates in the Capital Valley Conference of the Sac Joaquin section.

Many athletes have been signed from Inderkum into athletic scholarships. Since 2007, Inderkum has been the undefeated league champions in football every year except for 2012. They were the league champions in 2012, simply not undefeated in league. In 2006, Inderkum made the football playoffs for the first time and lost to Del Campo in the Semifinal round. Every year since then, they have made it into at least the 2nd round of the playoffs and have been in the third round or later of the playoffs every season since 2012.
