School Nutrition Dietary Assessment Study III, Volume I: School Food Service, School Food Environment, and Meals Offered and Served
Bibliographic record
Abstract
SNDA-III provides detailed information on the operation of school meal programs, the school environment that affects these programs, the nutrient content of school meals, and the contribution of school meals to students’ diets. Mathematica collected data for the study during school year 2004-2005 from a nationally representative sample of districts, schools, and students. This summary report notes that in a typical week, more than 70 percent of schools served meals that met standards for key nutrients, including protein, iron, calcium, and vitamins A and C. However, few schools met all nutrition standards, particularly those for fat, saturated fat, and calories. Most students had an opportunity to select a low-fat lunch but did not. In addition, foods sold in competition with United States Department of Agriculture school lunches were widely available—on an average school day, about one-quarter of students obtained food or beverages in school other than the regular school lunch.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
