Type(1): A 2-year experimental design research evaluation
of Math Recovery® was conducted from 2007-2009 in 20 elementary school across five school districts
in two states (Smith et al., 2013). In all, 343 children received one-on- one Math Recovery®
intervention over the two years.
Findings (1): As a diagnostic program, effect sizes were found to be between +0.30 and +0.40 for
students participating in Math Recovery® intervention.
Type(2): A longitudinal study of the effects of Mathematics Recovery from 1999 - 2004 at
Roye-Williams Elementary School (RWES), a Title 1 school in Harford County, Maryland.
Findings (2): Prior to the implementation of Math Recovery®, only 30-40% of children scored
proficient or better in mathematics on the Maryland state assessment program (MSPAP). In 2004, the
fifth year of implementation, 76.6 % of fifth grade children were proficient or better in
mathematics on the Maryland State Assessment (MSA); 82.9% of fourth grade children scored
proficient or better with 22.9 % scoring advanced; and 72.8
% of third grade children scored proficient or better.
The Mathematics Recovery program is grounded in over 40 years of education research. For detailed
