The management of the ex-combatants’ social protection is analysed using the KPI methodology. For this analysis, five blocks of indicators are adapted: “input” – funding allocated to ex-combatants’ social protection; “output” – ex-combatants’ participation in social programs; “activity” – funding per recipient and final performance of social protection; “mechanism” – administrative efforts required to achieve the intended outcomes; “control” – effectiveness of ex-combatants’ social protection compared to other population groups. The methodology has been tested in Ukraine using a system of 28 indicators available in 2020-2023. The lowest efficiency is typical for input indicators, mainly support programs funding (0.153 in 2022), the highest values were observed for activities indicators (ranging from 0,609 to 0.871). However, the essential distance from maximum level of 1.0 is obvious for all indicators. This approach allows for identifying existing gaps and opportunities to improve public management of ex-combatants’ social protection.
