Abstracts in English, Zulu and Swazi / This study aimed to investigate and find strategies that might improve School A's Grade 12 results through the principal's visionary leadership. The theoretical framework that informed this study was the school principal as a visionary leader, which plays a critical role in ensuring the quality of teaching and learning is improved by providing necessary resources for teachers and learners and creating a sound culture of teaching-learning. Upper Echelon Theory's effectiveness is based on strategic choices by visionary leadership and school performance principles that served as the theoretical framework. A qualitative research approach was used for this study, as it allowed the researcher to conduct in-depth interviews with ten school principals in Ehlanzeni District, Mpumalanga, and examined relevant documents to collect data. The research indicates that most schools acknowledge the importance of visionary leadership and proved that there were many execution gaps in implementing the intervention strategies that needed to be addressed, such as lack of effective visionary leadership, lack of unity, support to teachers, monitoring of teaching and learning and recruiting quality teachers in Grade 12. The study recommends that school principals need to implement more effective leadership, strategic planning and implementation of policy, communication, parental involvement accountability, effective monitoring and placement of quality teachers to teach Grade 12 learners. / Izindlela ezsetshenziswa ngothisha-nhloko abanobuholi obubhekela phambili ekwenzeni ncono izinga lokuphumelela ebangeni leshumi nambili kuzikole ezinemiphumela emihle. Lolucwaningo lugcile ekufunisiseni izindlela ezingenza ncono izinga lokuphumelela ngamalengiso ebangeni leshumi nambili ngokuholwa ngothisha-nhloko ababonela phambili izinto.Lolucwaningo lusekelwe ngolwazi olutholakele kwabanye ababonise ukuthi ubukhona bukathisha-nhloko obukela izinto phambili budlala inzima enkulu ekucinisekiseni ngezinga eliphezulu lokufundisa nokufunda ngoku nikeza izinsiza zokufunda nokufundisa kubothisha nakubafundi kanye nokwakha isiko lokufunda nokufundisa .I- ‘Upper Echelon Theory’, ukuphumelela kwayo kusekeleke kuzindlela nakuncubo-mgomo yabaholi abanombono. Lolucwaningo olukhethekile lokuthola ulwazi ngokukhulumisana nalabo abathinteka-ngco ivumela ukuthi uhlolo lwenziwe ngendlela yamanje yobuchwepheshe ngokukhulumisana nabothisha-nhloko abalishumi kusiyingi sase- Ehlanzeni, e-Mpumalanga, nokuthola eminye lanemininngwane ezincwadini zesikolo . Lolucwaningo luthole ukuthi abahlanganyeli abaningi bavumelana ngokuthi othishanhloko abanemibono babalulekile ekucinisekiseni ukuthi izindlela ezintsha zokuphumelelisa imiphumela; ukuncenga othisha abasezingeni eliphezulu kudinga ukwakhiwa .Lolucwaningo lusekela umbono wokuthi izikolo zidinga othisha –nhloko abazocinisekisa ukusethenziswa kwezindlela ezintsha kanye neku heha othisha abasezingeni eliphezulu ukuze bafundise abafundi bebanga leshumi-nakubili ukuze kukhushulwe imiphumela yebanga leshumi nakubili. / Tindlela letisentjentiswa ngubothishela-nhloko labanemibono kwenta ncono lizinga lekuphumelela ebangeni lelishumi-nakubili etkolweni letinemiphumela lemihle. Lelicwaningo ligxile ekufunisiseni tindlela letingenta ncono lizinga lekuphumelela ngemalengiso elibangeni lelishumi nakubili Lelicwaningo lelikhetsekile lokutfola lwati ngekucocisananalabo labatsintseka-nco kuloko lokukhulunyiswana ngako, ivumela nekutsi lokucocisana kungentiwa ngetindlela tamanje tebuchwepheshe ngekukhulumisana nabothishela-nhloko labalishumiesiyingini sase-Ehlanzeni, eMpumalanga, nekutfola leminye mininngwane etincwadzini tesikolwa letigciniwe. Lelicwaningo litfole kutsi labahlanganyeli kulelicwaningo bayavumelana ngekutsi bothishela-nhloko lababukela tintfo phambili babaluleke kakhulu ngobe ngibo labacinisekisa kutsi kusetshentiswa kwetindlela letisha nekuheha bothishela labasezingeni lelisetulu kuyayikhuphula miphumela yetikolwa. ngekuholwa ngubothishela-nhloko lababonela tintfo phambili. Lolucwaningo lutfole kutsi kuliciniso kutsi bothishela-nhloko lababonela tintfo phambili bayakwati kutsi kuheha bothishela labasezingeni lelisetulu nekusebentisa tindlela letihlukahlukene ekufundziseni kuyayi phakamisa imphumelelo yebafundzi nemiphumela yesikolo. / Educational Management and Leadership / M.
