InsideSchools.org is a comprehensive source of information on New York City schools visited by over 140,000 students, parents, educators, and members of the public each month. Its user-friendly website offers detailed profiles of New York’s 1,700 schools, including in-class videos, student achievement statistics, and insights gained from on-site visits. News and advice columns also cover everything from entrance tests to new administrative appointments. To ensure access by diverse demographic groups, the entire site can be immediately translated into 50 different languages. The Sloan Foundation has supported InsideSchools since its inception in 2002.Funds from this grant support efforts by InsideSchools to expand its offerings by providing information about the different pedagogical and curricular offerings at each school, such as Everyday Math, TERC, Saxon, Singapore, or Montessori. In a separate effort to improve data quality, InsideSchools will also begin consulting with a statistician to help separate school effects from small sample biases or other confounding variables.
