CAN ACCESS BALANCE THE EFFECT OF POVERTY?
Predictors of NAEP grade 4, 2007, 51 states
predictors | beta | t | P |
Poverty | -0.72 | 7.42 | 0 |
Access | 0.53 | 1.62 | 0.055 |
r2 = .63
Access = bks/student in school libraries, circulation in public libraries
Predictors of PIRLS:
Predictors of the reading test: PIRLS 2006
predictor | | P |
poverty | -0.41 | 0.005 |
independent reading in school | 0.16 | 0.14 |
library: 500 books | 0.35 | 0.005 |
Instruction | -0.19 | 0.085 |
r2 = .63

Replication: PIRLS 2011
Predictor | beta | p |
SES | 0.52 | 0.01 |
library: 5000 bks | 0.20 | 0.08 |
class libr | 0.08 | 0.28 |
parent read | 0.065 | 0.31 |
early lit | -0.26 | 0.04 |
Instruction | -0.016 | 0.5 |
r2 = .62
Note: Parental reading and classroom library correlated with PIRLS reading scores, but the effect disappeared in the multiple regression.
Note: Poverty and access are the main predictors of reading achievement in all studies.
