Impact of school SES on literacy development

Area of Science:

• Education
• Developmental Psychology
• Sociolinguistics

Background:

• Literacy is crucial for societal participation.
• Limited research exists on contextual variables influencing literacy development.
• School socioeconomic status (S-SES) is a potential factor affecting literacy achievements.

Purpose of the Study:

• To investigate the effect of school socioeconomic status (S-SES) on children's literacy.
• To determine if S-SES influences literacy skills beyond familial socioeconomic status (SES).
• To explore the role of cognitive and linguistic skills in mediating the S-SES effect.

Main Methods:

• Study involved 878 2nd and 4th graders in low-SES (vulnerable) and mid-high-SES (non-vulnerable) schools in Spain.
• Data collection included language, cognitive, and literacy tasks in Catalan.
• Statistical analyses controlled for familial SES and other covariates.

Main Results:

• Children in non-vulnerable schools outperformed those in vulnerable schools across all literacy competencies.
• Higher-order literacy skills, such as text quality and reading comprehension, were particularly affected by S-SES.
• The influence of S-SES diminished significantly when children's cognitive and linguistic skills were accounted for.

Conclusions:

• School SES affects student literacy skills independently of home SES.
• Cognitive and linguistic skills are key determinants of literacy performance.
• Educational interventions should focus on enhancing these actionable, subject-level skills.
