GCSE results in NI will be solely based on grades provided by teachers, the education minister has said.
There was controversy last week after more than a third of A-level and As-level grades provided by schools were lowered by the exams board CCEA.
Schools were asked to give predicted grades but then other data was used by CCEA to standardise the results.
Education Minister Peter Weir has now said standardisation will not apply to GCSEs.
Peter Weir said GCSEs taken with exams body CCEA - which provides about 97% of GCSE exams in Northern Ireland - would be covered by the decision.
"Having received advice from CCEA and listened to the concerns of school leaders, teachers, parents and young people, I have decided that all GCSE candidates will now be awarded the grades submitted by their centre," he said.
"Standardisation is normally a key feature of awarding qualifications in Northern Ireland and across the UK.
"However, these are exceptional circumstances and in exceptional times truly difficult decisions are made.
"I am conscious that for GCSEs, unlike at A-level, we do not have system level prior performance data for this group of young people."

He said he was acting to "ease anxieties" and "reassure young people and their families".
"I am also mindful that unlike A-Level, many GCSE pupils will not have access to previous public examination outcomes to inform any appeals process," he added.
CCEA said it welcomed the minister's decision.
"We will work immediately to implement this decision, with GCSE results published on Thursday 20 August 2020," it said.
There has been widespread criticism of the system used to determine A-level and AS-level grades.
On Sunday, a majority of the Stormont parties backed a move to recall the assembly to try to address the dispute over exam results in Northern Ireland.
SDLP leader Colum Eastwood, whose party proposed the motion, said students had been "badly let down by the education minister and CCEA who continue to slavishly prioritise process over the prospects of thousands of young people".
"The notion that the integrity of qualifications can be maintained when the reputation of the examining board and the Department is in tatters is extraordinary," he said.
How were A-levels decided?
Following the cancellation of exams in March due to the coronavirus pandemic, CCEA was instructed by Mr Weir to ensure the calculated results in 2020 were broadly in line with performance in recent years.
CCEA asked teachers to give a predicted grade for their pupils and then rank them in order within each subject.
It then used other data to standardise the results. For A-levels, the model used pupils' AS-level results and resit data.
According to CCEA, in 37% of cases this year teachers were overly optimistic in their prediction, affecting about 11,000 grades.
In about 5% of tests teachers underestimated the result, meaning that about 1,500 grades rose as a result of standardisation.
CCEA said if teacher judgement had been used on its own, results would have risen "considerably".
Mr Weir said the move on GCSEs would not change the approach that was taken on A-levels.
He said: "Unlike GCSEs, they were standardised on the basis of candidates' prior performance in public examinations.
"I would encourage those pupils dissatisfied with their result to contact their school or college to work through the appeals process which is free this year.
"As the appeals process is now underway, I am monitoring the outcome of appeals very closely to ensure that fair results are restored. CCEA has advised that extra resources are already being deployed to ensure that as part of a robust process the appeals will be dealt with both efficiently and effectively."
