This paper illustrates the central role of persistence in estimating and interpreting value-added models of learning. Using data from Pakistani public and private schools, we apply dynamic panel methods that address three key empirical challenges: imperfect persistence, unobserved heterogeneity, and measurement error. Our estimates suggest that only one-fifth to one-half of learning persists between grades and that private schools increase average achievement by 0.25 standard deviations each year. In contrast, value-added models that assume perfect persistence yield severely downward estimates of the private school effect. Models that ignore unobserved heterogeneity or measurement error produce biased estimates of persistence. (JEL I21, J13, O15)

Background: School uniform options such as skirts and dresses can impact physical activity and psychological wellbeing of girls. Restrictions that exclude trousers/pants or shorts as uniform options for girls can promote inequality in comfort and engagement in school activities. The South Australian Department of Education and Child Development (DECD) School Dress Code Procedure mandates school dress codes provide flexible uniform options with the right to choice, regardless of gender. This review examines public school adherence to DECD guidelines, and compares girls’ uniform options between public and private school sectors.Method: The proportion of girls shorts and pants/trouser options provided in school uniform policies collated in 2018 were compared across 486 public and 193 private primary, secondary, and combined schools within South Australia. Policies were grouped based on the choice they provided girls for shorts, and separately for trousers/pants. The groups were gender specific choice/open choice, unisex choice, restricted choice, or no option.Results: Overall, 98.6% of public and 26.4% of private school policies included shorts as a uniform option for girls. Of these schools, about nine in ten public, and just over half private, policies listed gender-specific or open choice shorts options. All public primary and high schools, and a majority of combined schools (98.8%) provided girls pants/trouser options, with 93.4% providing gender specific or open choices. This compared to 34.2% of private school policies including girls’ pants options. In total less than 1.0% of public, and 45.5% to 66.7% of private schools provide no opportunity for girls to wear shorts every day. Similarly, 56.0% of private schools do not provide any trouser/pant option.Conclusion: The results highlight a small proportion of public schools fail to follow mandated uniform policy procedures set by the DECD, specifically in context of shorts. Moreover, this report clearly demonstrates the discrepancy in girls’ uniform options between the public and private school sectors. We present suggestions and recommendations with the aim to improve current policy, as well as a need to advance adherence to policy and South Australian anti-discrimination legislation in public and particularly private schools.

Despite years of research and debate, household choice between public and private schools is not well understood. This article investigates factors associated with parental choice between public and private schools using unique census-based school enrollment data for school districts in South Carolina and for neighborhoods in the Columbia Metropolitan Area. This study extends the existing literature by examining patterns of public-private school choice for whites and blacks separately in order to control racial disparities in school choice. Results of multiple regression analyses for the whole population and subdivided racial groups generally support the assumption that public-private school enrollment rate is subject to socioeconomic status, racial proportion, and public school quality. Findings of this study not only suggests the reconciliation of the market-based theory and the racial preference theory, but also provides insights into education policies in terms of stemming white enrollment losses and fostering public school education in the United States.

In this article, the authors provide a methodological critique of the current standard of value-added modeling forwarded in educational policy contexts as a means of measuring teacher effectiveness. Conventional value-added estimates of teacher quality are attempts to determine to what degree a teacher would theoretically contribute, on average, to the test score gains of any student in the accountability population (i.e., district or state). Everson, Feinauer, and Sudweeks suggest an alternative statistical methodology, propensity score matching, which allows estimation of how well a teacher performs relative to teachers assigned comparable classes of students. This approach more closely fits the appropriate role of an accountability system: to estimate how well employees perform in the job to which they are actually assigned. It also has the benefit of requiring fewer statistical assumptions—assumptions that are frequently violated in value-added modeling. The authors conclude that this alternative method allows for more appropriate and policy-relevant inferences about the performance of teachers.

This article presents the first value-added model of private school effect in Ethiopia, using the unique Young Lives longitudinal data. I found a substantial and statistically significant private school premium (about 0.5 standard deviation) in Maths, but not in Peabody Picture Vocabulary Test (PPVT). Private school premium works for both low and high ability children. The results are robust to sorting on unobserved ability, grouping on lag structures and transfer between private and public schools. Combined with available contextual data, empirical evidence suggests that the effectiveness of private primary schools may be due to more learning time and teacher’s attention enjoyed by students. I also attempted to contribute methodologically to the literature by directly testing the structural assumption underpinning value-added models.

In the view of increasing preference of private schooling in India, this article assesses its impact on learning outcomes for rural children from 8 to 11 years. Despite earlier attempts to study the issue, this article stands out in two ways. Firstly, it addresses the problems arising because of non-random selection of children attending private schools. Secondly, it also presents an all-India estimate unlike most studies which have dealt largely with few states. Our results show the performance of children attending private school to be significantly better than those from public schools. This difference is evident among ‘low-fee’ private schools as well. However the private schooling premium differ across regions and groups, and there are several other concerns regarding affordability, access and segregation which require further deliberation and debate.

ABSTRACT Objective: To compare and analyze the consumption of minimally processed and ultra-processed foods among students from public and private schools. Methods: Study conducted in Uberlândia, MG, with fifth-grade students from three private and six public schools, selected by stratified cluster sampling. We collected data on food consumption using the 24-hour recall. Foods were classified into four groups (G) according to extent and purpose of processing: fresh/minimally processed foods (G1) culinary ingredients (G2), processed foods (G3), and ultra-processed foods (G4). Total energy intake (kcal) of each group, amount of sugar (g), sodium (mg), and fiber (g) were quantified and compared according to administrative affiliation (private or public). Results: Percentage of total energy intake was: G1 - 52%; G2 - 12%; G3 - 5%; e G4 - 31%. Energy intake from G1 (53 vs. 47%), G2 (12 vs. 9%), and G3 (6.0 vs. 0.1%), and amount of sodium (3,293 vs. 2,724 mg) and fiber (23 vs. 18 g) were higher among students from public schools. Energy intake from G4 (36 vs. 28%) and amount of sugar (20 vs. 14%) were higher among students from private schools. The consumption of foods from G1 in the school environment was higher among students from public schools (40 vs. 9%). Conclusions: Foods from G1 represent the highest percentage of total energy intake, while those from G4 constitute a third of calories consumed. Processed juice, sandwich cookie, processed cake, and breakfast cereals are more frequent among private school students; snacks and juice powder are more common for students from public schools.
