The focus of this First Look report is on base-year contextual data from the High School Longitudinal Study of 2009 (HSLS:09). This First Look is intended as a companion to the report, "High School Longitudinal Study of 2009 (HSLS:09): A First Look at Fall 2009 Ninth-Graders (NCES 2011327)" (ED521115), which focuses on the mathematics assessment and student beliefs, expectations, and exposure to different mathematics and science courses. This companion report introduces the contextual data provided by ninth-graders' parents, mathematics and science teachers, school counselors, and school administrators. The analyses examine parents' educational expectations for their ninth-graders as well as savings for postsecondary education; teachers' preparation and experience; and school administrators' challenges in managing students' schools across students' socioeconomic and academic backgrounds. The findings presented here are a small sample of the rich and extensive data that are part of the High School Longitudinal Study of 2009 (HSLS:09). Appended are: (1) Technical Notes and Methodology; and (2) Standard Error Tables. (Contains 26 tables and 3 footnotes.)
