School choice

Overview

  • Influence: School choice
  • Domain: School
  • Sub-Domain: School compositional effects
  • Potential to Accelerate Student Achievement: Likely to have a small positive impact
  • Influence Definition: Often traced to an argument made by economist Milton Friedman in 1955, school choice is premised on the belief that parents should have control over the kind of school their child attends. In the United States and elsewhere, this choice today often takes the form of vouchers: government funding that can be withdrawn from a particular public school and follow a child to a charter school or academy.

Confidence

The Confidence is the average of these four measures, each divided into five approximately equal groups and assigned a value from 1 to 5 based on the following criteria:

  • Number of Meta-analyses
    • 1 = 1
    • 2 = 2–3
    • 3 = 4–6
    • 4 = 7–9
    • 5 = 10+
  • Number of Studies
    • 1 = 1–10
    • 2 = 11–50
    • 3 = 51–200
    • 4 = 201–400
    • 5 = 400+
  • Number of Students
    • 1 = 1–2,500
    • 2 = 2,501–10,000
    • 3 = 10,000–20,000
    • 4 = 20,000–100,000
    • 5 = 100,001+
  • Number of Effects
    • 1 = 1–100
    • 2 = 101–300
    • 3 = 301–600
    • 4 = 601–1,200
    • 5 = 1,200+
