1 Early Selection in Hungary A Possible Cause of High Educational Inequality Daniel Horn research fellow Institute of Economics, Hungarian Academy of Sciences and Department of Economics, Eötvös University Budapest horn@econ.core.hu

2 Motivation Age of selection is likely the best proxy for comprehensive schooling – The later the first age of selection the longer students will study in heterogeneous groups Comprehensive schooling is said to be decreasing inequality (Meghir and Palme 2005, Pekkarinen, Uusilato and Kerr 2007) – and tracking correlates with higher inequality across countries (e.g. Hanushek and Woessmann 2005, Pfeffer 2008, Horn 2009) Why? – Teachers matter (Hanushek, Rivkin and Kain 2005; McKinsey 2007) – Peers matter (Sacerdote 2001, Hanushek et al 2003.) – … So the longer one studies in selected groups the larger the difference will be The Hungarian system is an „ideal” case for testing early selection

3 Inequality in the Hungarian education system is especially high Source: OECD PISA 2009 Vol. II, p 44. The system of education is certainly not comprehensive

ISCED 3a (technikum) 1 vocational training track ISCED 3c (ex-apprentice training) Age3456789101112131415161718 Early-selective tracks 8-yr-ac and 6-yr-ac

5 Questions Are early-selective tracks status selective? Do early-selective tracks have a higher value-added? Do longer, 8-year-long academic tracks further increase differences, as compared to the 6-year-long academic tracks? Do others lose because of the early selection? If answers are affirmative the early selective tracks increase initial differences between students of different status. Thus, the Hungarian system is more unequal (ceteris paribus) because of the early selection.

6 Data National Assessment of Basic Competencies (NABC) – Annually collected since 2006, PISA-like survey of all 6th, 8th and 10th grade students (see below) – Reading and mathematical literacy – Approximate mean: 1500, sd: 200 (before 2010: 500/100) Cross cohort and cross year comparable. Mean 1500 and sd 200 is only for 2008. 6th grade I standardize these, 0 mean 1 sd, for each year, cohort and subject – Detailed background questionnaires generated Socio-economic status (SES) index – 0 mean 1 sd – Individual panel since 2008

12 ARE EARLY-SELECTIVE TRACKS STATUS SELECTIVE? 1st question YES! (DETAILS IN THE PAPER, DUE TO TIME CONSTRAINT – SORRY!)

13 DO EARLY-SELECTIVE TRACKS HAVE A HIGHER VALUE-ADDED? DO LONGER, 8-YEAR-LONG ACADEMIC TRACKS FURTHER INCREASE DIFFERENCES, AS COMPARED TO THE 6-YEAR-LONG ACADEMIC TRACKS? (6TH TO 8TH GRADE) 2nd and 3rd question

14 The model Model: where, i-individual, s – school (track), t – time Y – test score, X – student charactersitics – SES, Gender Z – school characteristics – track type, ed. provider (FE) Endogenity problem – if Z st = Z s(t-1) – Thus if students do not change tracks during observations, track has an effect on Y (t-1) as well – students start general tracks six years, and 8-yr-ac tracks two years earier than we measure them. Thus 6th grade test scores reflect the quality of the given track Note: 6-yr-ac value-added is unbiased

15 Endogenity problem Sollution: Instrumental variable estimation – instrument: distance from home to nearest 6-yr-ac and 8-yr-ac – assumption: distance has an effect on the chance to enter an early-selective track, but it does not affect test scores Problem with instrument: – correlates with average SES establishment of early selective tracks was demand driven – correlates with average teacher quality teachers are also selected; just as students Easing the problem – Spliting the sample decreases the bias 8-yr-ac vs. 6-yr-ac and 6-yr-ac vs. general – Track effects in IV estimation are underestimated: the stronger the correlation bw. distance and teacher quality the more effect the instument „absorbs”.

19 DO OTHERS LOSE BECAUSE OF THE EARLY SELECTION? 4th question YES, IN MATH. Students in general schools, where early-selective tracks are available perform worse in math bw. 6th and 8th grade, compared to students in general schools with no early-selective track around.

20 Conclusion

21 Early selective tracks are status selective (6-yr-ac tested) Early selective tracks have a higher value added – between 6th and 8th grade in reading – between 8th and 10th grade in math 8-yr-ac performs better than 6-yr-ac in math each year Students left in general tracks lose Early selection increases the gap between students of different social background
