Every written Abitur exam in Germany is checked by a second teacher as well. The education ministers of the states agreed on it. In Saxony, a ministry notice in force from 2009 to 2015 even fixed the colors. The first marker corrected in red and the second in green. If a third marker had to decide, that teacher used brown. None of them was allowed to write points into the exam paper itself. In Baden-Württemberg, the second marker comes from another school chosen by the school authority. In 2014, a court in Freiburg limited the power of the final marker there. A student’s two marks had been 9 and 8 points, and the final marker gave 4. The court held that the final marker may override the first two only if one of their marks was unlawful. It set the grade at 9.
