Based on the 2014 National Competence Assessment data the study analyses the mathematical and reading competences of students in Jász-Nagykun-Szolnok County in comparison to other counties. In general the students in Jász-Nagykun-Szolnok County achieved lower results than the students in other counties. The proportion of schools with a higher proportion of Roma students is relatively high in the county. However, the competence assessment results are explained by the social status of the students’ families in first place. The pedagogical added-value compares the competence assessment results to the social background of the students. However, the schools of the county lag behind other counties in this aspect as well. In the county the four- and eight yearsecondary schools and vocational high schools show a positive added value, other types of schools achieve lower results than expected.
