True or False? Two schools with roughly the same mix of students can spend the same amount money and get different results. True False Two schools with roughly the same mix of students can spend the same amount money in the same way and get different results. True False Why? The “school effect.” EDUNOMICS LAB AT GEORGETOW N UNIVERSITY 4 EDUNOMICS.GEORGETOW N.EDU

What is productivity? • “Productivity” involves raising outcomes for a given expenditure Outcomes ---------------------- Inputs ($) “Efficiency” generally refers to achieving the same outcomes at a lower expenditure. EDUNOMICS LAB AT GEORGETOW N UNIVERSITY 5 EDUNOMICS.GEORGETOW N.EDU

Rural districts vary on spending, outcomes and ROI .

20 years research: Frustrating Finding: Expenditure choices don’t explain as much of the variation as we’d hoped. What does? • Ownership. (It yields human/school effects) • Understanding tradeoffs. (Financial transparency helps here) • Benchmarking with data (spending and outcomes). 7

What do you prefer? (survey by Goldhaber & DeArmond) $5K bonus or 2 fewer students in each class you teach 83% $5K bonus or 1/5 of an aide 88% $5K bonus or 3.5 hours more prep time per week 69% 8

In context of limited resources, some schools much better at producing outcomes than others. View District Schools High Spend. Low Spend. High Outcomes High Outcomes High Spend. High Low Spend.
