The Upstream Project Canada: An Early Intervention Strategy to Prevent Youth Homelessness & School Disengagement
Bibliographic record
Abstract
Upstream Canada is a response to this challenge and the staggering reality that 35,000 – 45,000 youth in Canada experience homelessness each year (Gaetz, 2016). This initiative is a preventive approach to the problem that works to offer supports to youth ages 12-18 who are identified as at risk of homelessness and school disengagement through a universal screening tool called the Student Needs Assessment (SNA). This universal approach sets Upstream Canada apart from other interventions as it identifies students who do not display outward signs of risk and experience barriers to accessing help. Upstream Canada is an adaptation of work that originated in Australia as The Geelong Project (since renamed Upstream Australia), which has demonstrated a 40% reduction in youth homelessness three years after implementation. As an equity-focused early intervention that works through the collective efforts of schools and community-based organizations, Upstream Canada works to prevent youth homelessness and early school leaving.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
