Mae consensws cryf bellach wedi dod i'r amlwg mewn tystiolaeth academaidd sy'n dangos effeithiau cadarnhaol mawr gwariant ysgolion, gydag effeithiau mwy ar ddysgwyr difreintiedig. Dylai penderfyniadau polisi a gwariant ar bob haen o lywodraeth adlewyrchu'r dystiolaeth hon. Os bydd cyllidebau'n caniatáu, mae hyn yn debygol o awgrymu lefelau uwch o gyllid amddifadedd i ysgolion.
A strong consensus has now emerged in academic evidence showing large positive effects of school spending, with larger effects for disadvantaged learners. Policy and spending decisions at all layers of government should reflect this evidence. Should budgets allow, this is likely to imply higher levels of deprivation funding for schools.
