The　study　provides　thresholds　of　income　inequality　that　if　exceeded　will　nullify　the　positive　effect　of　governance　dynamics　on　gender-inclusive　education　in　42　countries　in　sub-Saharan　Africa　for　the　period　2004–2014.　The　Generalised　Method　of　Moments　is　used　as　an　estimation　strategy.　The　following　findings　are　established.　First,　the　unconditional　effects　of　governance　dynamics　on　inclusive　education　are　consistently　positive　whereas　the　corresponding　conditional　effects　from　the　interaction　between　inequality　and　governance　dynamics　are　consistently　negative.　Second,　the　levels　of　inequality　that　completely　crowd-out　the　positive　incidence　of　governance　on　inclusive　‘primary　and　secondary　education’　are:　0.587　for　the　rule　of　law　and　0.565　for　corruption-control.　Third,　the　levels　of　inequality　that　completely　dampen　the　positive　incidence　of　governance　on　inclusive　‘secondary　education’　are:　0.601　for　‘voice　&　accountability’　and　0.700　for　regulation　quality.　Fourth,　for　tertiary　education,　inequality　thresholds　are　respectively　0.568　for　political　stability　and　0.562　for　corruption-control.　The　main　policy　implication　is　that　for　governance　dynamics　to　promote　inclusive　education　in　the　sampled　countries,　income　inequality　levels　should　be　kept　within　the　established　thresholds.　Other　implications　are　discussed　in　the　light　of　Sustainable　Development　Goals.　©　2020　The　Association　for　Social　Economics.
