This report was developed in partnership with Ready At Five. It lays out the critical importance of children starting school fully prepared to succeed in kindergarten. Most importantly, the report shares what everyone has learned from the 2010-2011 Maryland Model for School Readiness (MMSR) data about the school readiness of Maryland's children: statewide, by subgroups, and for each of Maryland's 24 local jurisdictions. Some of the highlights are: (1) The percentage of Maryland kindergarteners fully ready to start school increased to 81% in 2010-2011, up 3 points from 2009-2010. This met Maryland's expectation for this year's again, and it continues the remarkable 32-point increase of the past 10 years, which began with school readiness at 49% in 2001-2002; (2) Maryland experienced pronounced gains in school readiness across all Domains of Learning. In the core cognitive Domains, the State saw a 35-point increase from 2001-2002 in Language and Literacy (71% fully-ready for 2010-2011), a 35-point improvement in Mathematical Thinking (75% fully-ready), and a 44-point jump in Scientific Thinking (68% fully-ready); (3) African American kindergartners made statistically significant increases: 76% of African-American children are fully school-ready, up from 37% in 2001-2002 and 71% in 2009-2010; (4) The percentage of kindergarteners from low-income households (as indicated by Free and Reduced Price Meal status) who are fully school-ready rose from 34% in 2001-2002 and 69% in 2009-2010 to 73% in 2010-2011; (5) Children with disabilities made substantial progress: 56% are fully-ready, gaining 5 points from last year--2 points more than the statewide gains; and (6) Kindergartners attending public PreK the year prior to entering school continue to be well-prepared: 81% fully school-ready in 2010-2011.
