A more recent 2016 analysis by the politically independent think-tank Kraka concluded that students with a non-western background attending Muslim private schools achieved significantly better grades in their 9th grade exit examinations than their Muslim counterparts at Danish public schools. The difference between the students' final examination marks was 1.4 grade points–an average 4.6 at the public schools and 6.0 at the Muslim private schools.

The Government criticized the incidents and investigated several, but it brought few cases to trial specifically on charges of racial discrimination or hate crimes. Reports continued of incidents of desecration of ethnic and religious minority gravesites. Al-Faruq mosque In May 2017 an imam of the al-Faruq mosque in Nørrebro held a service where he preached a vision of the caliphate and the murder of Jews.
