Teenswoordig bestaan sekondêre onderwys in die meeste onderwysstelsels van die wêreld uit die tweede fase van formele onderwys wat tydens [[adolesensie]] plaasvind. Dit word gekenmerk deur die oorgang van die gewoonlik verpligtende onderwys vir minderjariges na die opsionele, selektiewe [[Tersiêre onderwys]] of [[Hoër-onderwys]] (bv. [[Universiteit]]e, [[Beroepsopleidingskool|Beroepsopleidingskole]] vir [[volwassene]]s). Die grens tussen primêre en sekondêre onderwys verskil van land tot land en soms selfs binne die grense van 'n land, maar die skeiding vind gewoonlik plaas rondom die aanvang van die tienerjare. Die doel van sekondêre onderwys is gewoonlik daarop gemik om voldoende [[algemene kennis]] te vestig ter voorbereiding o [[hoër onderwys]] of [[beroepsopleiding]].

===Secondary education===
{{main|Secondary education}}
In most contemporary [[educational system]]s of the world, secondary education consists of the second years of formal education that occur during [[adolescence]]. It is characterised by transition from the typically compulsory, comprehensive [[primary education]] for [[minor (law)|minor]]s to the optional, selective [[Tertiary education|tertiary]], "post-secondary", or "[[Higher education|higher]]" education (e.g., [[university]], [[vocational school]]) for [[adult]]s. Depending on the system, schools for this period or a part of it may be called secondary or high schools, gymnasiums, lyceums, middle schools, colleges, or vocational schools. The exact meaning of any of these varies between the systems. The exact boundary between primary and secondary education varies from country to country and even within them, but is generally around the seventh to the tenth year of education. Secondary education occurs mainly during the teenage years. In the [[United States]] and [[Canada]] primary and secondary education together are sometimes referred to as [[K-12]] education. The purpose of secondary education can be to give [[common knowledge]], to prepare for either [[higher education]] or [[vocational education]], or to train directly to a [[profession]].
