SAN DIEGO — One of the nation’s largest school districts has launched a campaign against Islamophobia, drawing both praise and criticism.

The San Diego Unified School District’s multiyear plan includes a letter addressing anti-Islam bias to staff and parents of its 132,000 students.

It’s expected to be drafted and sent before Ramadan begins in late May. The district is also reviewing internal staff calendars to make sure Muslim holidays are recognized.

Next school year, it will review materials on Muslim culture for libraries, provide resources to teachers, and engage in partnerships with the Council on American Islamic Relations. Over several years, it plans to consider high school clubs that promote US Muslim culture, create ‘‘safe spaces’’ for students, and train staff about Muslim culture.

The plan drew little attention when the board approved it 4-0 on April 4, with one member absent. Public comments from staff and community members were uniformly positive.

‘‘We believe this is a great first step in the direction of protecting Muslim students from the bullying that is a direct result of the growing Islamophobia in our state and nation,’’ Hanif Mohebi, executive director of the Council on American-Islamic Relations’ San Diego chapter, said after the vote. ‘‘Other school districts should follow this lead, and we will be happy to work with them to provide resources and trainings.’’

Pushback gradually spread on the internet and social media, with written attacks on Islam and the Council on American-Islamic Relations. A Sunday article on the far-right website Breitbart News drew hundreds of reader comments. The headline of a story on the Angry Patriot website that had 35,000 Facebook ‘likes’ read, ‘‘Islamic Takeover Confirmed — American School Surrenders to Sharia Law.’’
