Longer school days and Saturday classes could be used to help children catch up after months away from the classroom.
Education Secretary Gavin Williamson said teachers could decide if more time in the classroom was needed to get pupils up to speed on lessons missed during lockdown.
He told MPs that schools will assess the individual needs of their children, adding there is “clear guidance” about what works in the classroom.
Mr Williamson told the Commons: “That might mean extending the school day for some, that might mean Saturday classes for others.
“There are so many different interventions that can really deliver significant results in terms of helping youngsters catch up on the learning that they have lost.”
Millions of children began to return to the classroom full time in England at the start of September.
But some schools have already been forced to shut their doors due to outbreaks of coronavirus – and some year groups have been sent home to self isolate.
Samuel Ward Academy in Haverhill, Suffolk, closed on Monday after five teachers tested positive for the virus, with two more awaiting tests.
Mr Williamson insisted ministers were in control of their plan to get children back into the classroom despite outbreaks in schools.
Asked by Labour whether the Government had a grip on the crisis, he said: “Very much so and if I draw your attention to the joint-letter by the chief medical officers of England, Wales, Northern Ireland and Scotland, what they were pointing out is that children are best served by being in school.”
And he insisted that schools would only ever be closed as “last resort”.
The under-fire Education Secretary faced questions over the A-Levels fiasco after it emerged that ministers had been told about flaws in the grading system weeks before.
Shadow Education Secretary Kate Green said the Government was “repeatedly warned of the dangers of the system of calculated grades”, which saw thousands of results downgraded by a computer algorithm before ministers were forced to u-turn.
She added: “He was warned by a former senior official of the department, he was warned by the regulator, and warned by what happened in Scotland.
“Why did he ignore those warnings?”
But Schools Minister Nick Gibb insisted the Government had been assured the model was fair.
He said: “When the A-Level results were published on 13 August, it did become clear that there were anomalies and injustices that went beyond the anomalies that we had been made aware of for which we had put in place an enhanced appeals process.
“Swift action was taken to ensure that all young people got the just and fair results they deserve.”
Labour will attempt to force the Government to publish documents on the A-levels exams fiasco this week, the Mirror previously revealed.
