HOME Welcome to “The BEST Kept secret in Granada Hills”. Tulsa Elementary School of Advanced Studies sits in the heart of Granada Hills and is full of a community of caring students, parents, teachers and community members. As we move forward in our implementation of Common Core Standards it is my goal to make sure that we do so together as a team, which is why along with our teachers attending workshops we would like to continue to offer parents the opportunity to learn more about Common Core Standards. In preparing our students for excellence in the 21st Century we continue to strive for high academic achievement. It is our goal that we let the rest of LAUSD hear our Roar as we impact the Granada Hills community!!!
