In partial correlations in Illinois (Lance et al., 2005), some correlations were noted
between library media specialist staffing and student achievement. There was a significant
correlation at the fifth grade and eight grade when three of four school and community variables-
- household income, per pupil expenditure, teacher/pupil ratio and student ethnicity-- were used
as the control variable. At the 11th grade there was a statistically significant correlation when all
four school and community variables were included. No specific figures regarding these
correlations were published.
In Alaska, Lance et al. (1999) found a significant correlation between library staffing and
standardized tests in a regression analysis that included per pupil expenditures and teacher/pupil
