Social Position Indices of ERAs (from 2022)

The Social Position Index (SPI) makes it possible to apprehend the social status of pupils from the professions and social categories (PCS) of their parents. Each PCS or PCS couple is associated with a numerical value of the IPS. This numerical value is a quantitative summary of a set of socio-economic and cultural attributes related to academic achievement. The higher the Social Position Index (SPI), the more students are on average of favoured social origin. The weaker it is, the more socially disadvantaged the pupils are of origin. Concretely, the reference values of the index for each PCS, or pair of PCS, are determined using a statistical method that makes it possible to synthesize a set of characteristics describing the living conditions of students (see article by Rocher, 2016). The index of a given CSP is thus the quantitative summary of a number of socio-economic and cultural attributes related to academic success, which are found on average for this CSP. The first version of the index, used until the start of the 2021 school year, was calculated on the data of the DEPP panel of pupils who entered sixth grade in 2007. For these 35,000 students on the panel, there is rich information on their living conditions to establish the PCS-IPS transition table. At the start of the 2022 school year, this table of passage was updated by mobilising data from the DEPP panel of pupils who entered CP in 2011. Once the parents' CSPs are provided, which is the case for the vast majority of second-level students, it is sufficient to apply these reference values and consider this new variable as an index, that is to say, quantitatively. The social level of a school is assessed through the calculation of the average PSI of the students who attend it. It should be recalled that, like any synthetic index, it is a simplified summary of reality, which cannot by itself account for the complexity of the socio-economic and cultural situation of pupils in an establishment. As the IPS is based on the PCS declared by families and registered by establishments, it is subject to a certain margin of error: Thus, it is advisable not to over-interpret differences of 3 points or less concerning the average IPS of institutions. Finally, it should be noted that the methodology for calculating the index has changed, leading to a break in series from the start of the 2022 school year: the reference values of the index have changed and pupils whose GCVs of both parents are not filled in no longer enter into the calculation of the average GPI of their school (transition table available as an attachment below). The social heterogeneity index of an institution corresponds to the standard deviation of the social position index (SPI) of its pupils. The higher it is, the more diverse the social profile of students. This index has been calculated since the start of the 2019 school year, only for secondary schools. As for the calculation of the average IPS, from the start of the 2022 school year onwards, pupils whose GCVs of both parents are not specified are excluded from the scope of the calculation of the standard deviation. **_Field_** The file provides the average IPS within an institution as well as the standard deviation of the IPS of its students for the EREA of France under the supervision of the National Education, public and private under contract, calculated from the data of the school year N and for all students of the institution. The file also provides the ERA workforce from which the IPS is calculated. In the file made available, each line corresponds to an EREA for a given school year. **_Reference_** Rocher, T. (2016).
