Investment and Operation Expenditures Revisited

A few readers wrote to me asking for further clarification on the differences between investment and operation expenditures. For example, should a one-to-one initiative be classified as an operation or investment expenditure. This short post helps answer such questions. After reading Rethink District Budgeting Part I and Part II, it is apparent that all the new “budget dance” moves start with differentiating between operation and investment expenditures. While Table 1 can be readily applied to make the distinction for most expenditures, there are cases where the distinction is not that clear cut. For certain expenditures, people may have genuine differences […]

COMMENSURABILITY Assuming that we have obtained valid A-ROI estimates for multiple investments, there remain issues to be considered and addressed when using those results for investment comparisons and decisions. The issues center on the extent to which those different A-ROI estimates can be compared to gauge relative cost-effectiveness and, if the answer is yes, how to compare them properly. First, there is the issue of different outcome measures. For example, A-ROI is calculated for three investments that are intended to increase reading achievement, reduce suspension, and improve sense of belonging, respectively. It is apparently inappropriate to compare the results directly […]


Five Issues around Using Academic Return on Investment (A-ROI) to Inform and Improve Decisions: Part II – Uncertainty

In the first post of this series, I discussed validity of A-ROI as a measure of cost-effectiveness. In this post, I focus on uncertainty embedded in A-ROI results.

That is, for a three-year investment, the ROI result is a both accurate and precise representation of its profitability over those three years only. Consumers of ROI information are admonished about risks when applying it to the future or other contexts. Generally, little is provided about those risks other […]
