More than 700 000 candidates are expected to sit for the National Senior Certificate (NSC) examinations later in October.
This is 40 000 fewer than last year, the Umalusi Council for Quality Assurance in General and Further Education and Training said on Thursday.
"The council has conducted a thorough assessment of the readiness of the basic education system to manage and conduct the 2019 national examinations.
"To this end, the council is generally satisfied that all assessment bodies are ready to undertake this massive task," CEO Mafu Rakometsi said at a briefing in Johannesburg.
He was briefing the media on readiness for the end-of-year examinations.
The examinations will be conducted in more than 6 900 centres across various provinces from October 23 to November 28.
KwaZulu-Natal (KZN), Gauteng, Limpopo and the Eastern Cape have the highest enrolments.
However, the figures are still less than those in 2018:KZN: 147 935 (151 932 in 2018)Limpopo: 94 563 (96 834 in 2018)Eastern Cape: 82 113 (85 371 in 2018)
Gauteng is the only province which had an increase from 107 168 in 2018 to 111 474 in 2019.
But the audit, conducted by officials from the quality assurance board, identified a few concerns, namely a shortage of markers in subjects with high enrolments.
Although an interim contingency plan has been put in place to address these concerns, Umalusi is of the view that the issue requires attention from all affected departments of education.
The quality assurance board further identified high levels of vacancy rates in critical areas within examination directorates.
This includes Limpopo, the Northern Cape, Mpumalanga, the Free State, KwaZulu Natal, the North West and the Eastern Cape.
"Nevertheless, PEDs (provincial education departments) have put measures in place, such as allowing available staff to work overtime to mitigate the shortage of staff," Dr Rakometsi said.
The CEO gave his position on the much-debated proposed General Education Centre (GEC) by the Department of Basic Education.
"In principle, Umalusi supports the idea of a GEC, provided it is properly understood as a transitional qualification rather than an exit qualification.
"One of the advantages of the GEC is that it could provide valuable national data to gauge the performance of our education system. However, Umalusi will firstly evaluate the GEC qualification and then issue a formal statement on the outcome of that process," he said.
