The last decade "was characterised in Germany by ... changes with regard to integration policy... for example, the reform of the citizenship law which came into force in 2000, the introduction of integration courses throughout Germany as a result of the Immigration Law (2005) and the adoption of the National Integration Plan (2007). In this context, the question increasingly arises as to whether and how to determine the successes and failures of Germany’s integration policy." (Quoted from paper)
