Clarendon Alternative Elementary School Reviews

By a Parent on

Clarendon is one of the top 3 public elementary schools in San Francisco.  Both our kids love it!  The principle, Mr. Mark Barmore, makes a big difference to the quality of the school. (He is far, far better than the last principle who was horrible).  Parent participation is also very high as the fundraising numbers reflect.

One point to note.  There are two separate programs at Clarendon each comprising ~50% of students.  The first is called Second Community and is a regular Elementary program with Italian taught as an enhancement to the program.  The Second is the Japanese Bilingual Bicultural Program (JBBP) which is a Japanese language immersion program.  Both are top tier!
