The given pie chart depicts the percentage of the findings of a survey about the reasons for poor learning outcomes in schools in a specific region in 2011.
Overall, it is clear that the unskilled teachers were the highest cause for insufficient outcomes in learning, while lack of revision was the lowest cause for the same.
In 2011, more than a third of unskilled teachers accounted for the reason for failures in educational achievements. The way the children were brought up was the second reason for the bad outcomes during education, which was 27%, and a fifth of the parents had jobs that also caused poor results in schools.
The least reasons for inadequate results in the schools were inadequate infrastructure and lack of revision; moreover, one in ten complained about poor facilities in the schools, and only 8% of people blamed the lack of revision for below-average academic results.
