The Organisation for Economic Co-operation and Development (OECD) published a report where it compared the performance of 540,000 15-year-old students from 72 different countries.  This report was the PISA report for 2015.  According to this report, Germany is amongst the top twenty countries for education.  PISA is a survey that compares what citizens from around the world know and are able to do.  It focuses on international comparable evidence in student performance.   In Europe, Germany was amongst the top ten countries for student performance.  The fields researched in were science, reading and mathematics.

German students got the highest scores in reading and science, however, when compared to the report of 2012, scores decreased by 15% in science and in mathematics the scores did not change significantly.   On the other hand, Germany increased by one score in reading.  In the science category the German students were 3% higher than the OECD average making 11% of them top performers.  In Germany it was discovered that fewer girls than boys perform at Level 5 or more in science and even the top performing girls, are less likely expected to work in science related occupations.

Overall, German students got higher scores than the OECD average in all three domains assessed.  Across OECD countries, students attending advantaged schools scored more than students attending disadvantaged schools.  This s also very applicable in Germany where the performance between the two groups was of 42 points.  This is larger than the OECD average.
