Recently, I wrote about Tarek ibn Ziyad Academy (TIZA), a K-8 charter school in Inver Grove Heights. Charter schools are public schools and by law must not endorse or promote religion.

Evidence suggests, however, that TIZA is an Islamic school, funded by Minnesota taxpayers.

TIZA has many characteristics that suggest a religious school. It shares the headquarters building of the Muslim American Society of Minnesota, whose mission is "establishing Islam in Minnesota." The building also houses a mosque. TIZA's executive director, Asad Zaman, is a Muslim imam, or religious leader, and its sponsor is an organization called Islamic Relief.

Students pray daily, the cafeteria serves halal food - permissible under Islamic law -- and "Islamic Studies" is offered at the end of the school day.

Zaman maintains that TIZA is not a religious school. He declined, however, to allow me to visit the school to see for myself, "due to the hectic schedule for statewide testing." But after I e-mailed him that the Minnesota Department of Education had told me that testing would not begin for several weeks, Zaman did not respond -- even to urgent calls and e-mails seeking comment before my first column on TIZA.
