Intelligence test scores and educational duration are positively correlated. This correlation could be interpreted in two ways: Students with greater propensity for intelligence go on to complete more education, or a longer education increases intelligence. We meta-analyzed three categories of quasiexperimental studies of educational effects on intelligence: those estimating education-intelligence associations after controlling for earlier intelligence, those using compulsory schooling policy…

The influence of educational attainment on intelligence
Abstract Education has been found to have a positive influence on intelligence, but to be able to inform policy, it is important to analyse whether the observed association depends on the educational
The Moderating Influence of School Achievement on Intelligence in Young Adulthood
TLDR
Investigation of how school achievement, as measured by grade point average in lower secondary school at 15 years of age, moderated intelligence variation in young adulthood found shared environmental variance unique to intelligence was found to be greater among individuals with poor school achievement.
Intensive schooling and cognitive ability: A case of Polish educational reform
Abstract Intelligence is the most critical predictor of school successes, yet the length and quality of education influence cognitive development as well. Using data collected during the recent
Education and age-related decline in cognitive performance: Systematic review and meta-analysis of longitudinal cohort studies
TLDR
Overall, education is an important factor in aging due to its robust association with level of performance, but the current base of empirical evidence is not revealing a consistent and substantial association between educational attainment and changes in cognitive performance in the general population.
Education, intelligence and Alzheimer’s disease: Evidence from a multivariable two-sample Mendelian randomization study
TLDR
There is robust evidence for an independent, causal effect of intelligence in lowering AD risk, potentially supporting a role for cognitive training interventions to improve aspects of intelligence and support for policies aimed at increasing length of schooling to lower incidence of AD.
Influence of young adult cognitive ability and additional education on later-life cognition
TLDR
If cognitive gains reach an asymptote by early adulthood, then strengthening cognitive reserve and reducing later-life cognitive decline and dementia risk may really begin with improving educational quality and access in childhood and adolescence.
Intelligence and academic performance: Is it all in your head?
TLDR
Interplay between IQ, academic performance, and brain connectivity with behavioral and functional MRI data collected from undergraduate students as they completed an active learning or lecture-based semester-long university physics course provides evidence that physics classroom environment and pedagogy may have a gendered influence on students’ performance.
Inequality of educational opportunity at time of schooling predicts cognitive functioning in later adulthood
TLDR
It is suggested that IEO is able to substantially influence cognitive development with long-lasting impacts, and lower-educated women of the cohorts under investigation may have been particularly vulnerable to high-inequality educational contexts.
Education, intelligence and Alzheimer’s disease: evidence from a multivariable two-sample Mendelian randomization study
TLDR
There is robust evidence for an independent, causal effect of intelligence in lowering AD risk, and the causal effects of educational attainment is likely to be mediated by intelligence.
Education and Cognitive Functioning Across the Life Span
TLDR
It is found that associations between education and aging-associated cognitive declines are negligible and that a threshold model of dementia can account for the association between educational attainment and late-life dementia risk.

Age versus schooling effects on intelligence development.
The effect of formal education, as opposed to chronological age, on intelligence development has suffered from inadequate empirical investigation. Most studies of this issue have relied on natural

Prior research has shown that quantity of schooling affects the development of intelligence in childhood and adolescence. However, it is still debated whether other aspects of schooling--such as
Schooling in adolescence raises IQ scores
TLDR
It is found that a reform that increased compulsory schooling from 7 to 9 y in Norway in the 1960s to estimate the effect of education on IQ had a substantial effect on IQ scores measured at the age of 19 y.
Education is associated with higher later life IQ scores, but not with faster cognitive processing speed.
TLDR
Increased education may enhance important later life cognitive capacities, but does not appear to improve more fundamental aspects of cognitive processing, as measured at ages 83 and 70.
Is Education Associated With Improvements in General Cognitive Ability, or in Specific Skills?
TLDR
Results suggest a decoupling of educational gains from increases in general intellectual capacity, and the association of education with improved cognitive test scores is not mediated by g, but consists of direct effects on specific cognitive skills.

Benefits of educational attainment on adult fluid cognition: international evidence from three birth cohorts
TLDR
It is found that having a university education is correlated with higher fluid cognition in adulthood, after adjustment for adolescent cognition and the likelihood of earning a university degree depends in part on adolescent cognition, gender and parental social class.

TLDR
A cross-lagged panel analysis of Wechsler Intelligence Scale for Children-Fourth Edition (WISC-IV) intelligence test scores and reading and math achievement test scores of 337 students twice assessed for special education eligibility across a test-retest interval of 2.85 years found that g, reading, and math were stable across time and synchronously correlated.
