Scotland's pupils have returned to classes for the first time since lockdown began nearly five months ago.
Borders and Shetland schools are the first to reopen with most others following on Wednesday.
Physical distancing among students will not generally be required but hygiene and safety measures such as one-way systems have been put in place.
Except for children of key workers, most of the country's 700,000 pupils have not been in class since 20 March.

The Scottish government is warning that it could call a halt to the football season after a Celtic player breached coronavirus rules.
Boli Bolingoli admitted he played in Sunday's match against Kilmarnock despite having recently returned from Spain without quarantining.
The defender said he was "guilty of an error of judgement" and apologised.
Scottish Justice Secretary Humza Yousaf described the player's actions as "utterly unacceptable."
The breach comes after eight Aberdeen players apologised for visiting a bar at the centre of a Covid-19 outbreak.
Image source, PA MediaPupils and parents have told of their mixed emotions as Scottish schools become the first in the UK to reopen as lockdown is eased.
Pupils in the Scottish Borders have returned to school as have some in Shetland on a phased basis.
Alex Bisset, an S6 pupil at Kelso High School in the Borders, said he felt safe returning as extra hygiene measures had been put in place on campus.
But he was pessimistic about how long the school will remain open.
The 17-year-old from Birgham said: "I'm feeling quite happy that things are slowly returning to normal but at the same time I don't think it's going to last.
"I feel like in not too long there's going to be perhaps another outbreak and we'll all be sent home again."
Isla Findlay, an S5 pupil at the school, said she felt a little overwhelmed seeing so many of her classmates after five months of lockdown.
The 16-year-old from Kelso said: "I'm a bit nervous but, yeah, it will be good.
"It's just, like, what's going to be different? I'm happy to see all of my friends - just how are they going to handle everything? It's a bit scary.
"I'm feeling safe, it's just a lot seeing everyone again. I thought it would be a lot worse but it's nice to see everyone as it's been so long."

Unemployment up: employment down: with fewer job opportunities, fewer people making themselves available for work.
So, there are no surprises in the labour market figures for April, May and June - the most severe months of lockdown, with some easing in June.
However, it is a little surprising that the figures have not shifted more.
An unemployment rate of 4.5% remains low, given the extraordinary economic events since March. The UK rate, of 3.9%, is the same as last year.
It seems the Labour Force Survey, which results in the normal headline employment statistics, is failing to capture those events, mainly because those on furlough are not counted as unemployed.
Partly, that is because many will return to work when it is there for them to do, and partly because the scheme is delaying unemployment for others.

Ian Aitchison, from the National Parent Forum in the Borders, said he had no concerns about pupils in the area returning to school today.
"We have been very fortunate here, the parent body has had a great dialogue with the council, all questions have been answered and I'm very confident that all measures that can be taken have been taken."

To start with, even losing a confidence vote at Holyrood technically would not doom the education secretary. Unlike the government as a whole, there is no statutory requirement for a minister to go after losing such a vote - although in reality the pressure on them would be immense.
Ms Sturgeon has absolved the SQA of any blame, making it very clear that the buck stops with ministers.
Having come up with the idea, Scottish Labour are likely to push for a vote against Mr Swinney regardless of what he comes up with. The same is probably true of the Scottish Conservatives.
So his fate will ultimately lie in the hands of the Greens and the Lib Dems, who are both waiting to hear the detail of the statement.
Ms Sturgeon insists this is "not party political", and that she would look to do right by students regardless of any looming rebellion at Holyrood.
However, it is inescapable that she is a first minister facing an election in May, and who pegged education and boosting pupils from more deprived backgrounds as her number one priority for the current term of parliament.
If her government is seen to have dropped the ball on that very issue, months before voters go to the polls, it could be a lot more than the fate of Mr Swinney on the line.

Prof Paterson from the University of Edinburgh says he doubts whether the relationship between teachers and the exam body, the SQA, could be any worse.
"Essentially the SQA, a bunch of bureaucrats and statisticians, have said to teachers we don't trust your judgement and we are going to impose our statistical models on you," he says.
"That is absolutely not a way to run an education system," Prof Paterson says.
"Nicola Sturgeon said yesterday the fault did not lie with the SQA, it lies with her. She is wrong, it does lie with the SQA.
"If the fault did lie with government it would mean it was intervening in the assessment process which would be a completely inappropriate thing to do for government.
"The SQA seems completely impervious to taking any responsibility for this catastrophe."

Meanwhile pupils have started their return to classrooms - with students in Shetland and the Borders resuming lessons for the first time since the lockdown forced the closure of schools in March.
The main teaching unions have told BBC Radio Scotland some members are concerned about safety and consideration should be given to older students wearing face coverings.
Jill Lothian is head of Kelso High School - she says strict protocols are in place: "There's obviously hand sanitiser, there's one way systems in place and when the young people go into classrooms we're adhering to the 2m social distancing from the member of staff and wipes etc through every room."

Professor Lindsay Paterson warns there are no easy solutions to the grades crisis
Lindsay Paterson, professor of education at Edinburgh University, says there is no easy solution to the schools results crisis.
"Nothing John Swinney says today can satisfy everyone," he says.
Prof Paterson says that if there is evidence to back up a grade, such as a prelim which was done under proper exams conditions, then they could take the teacher's judgement on what grade to award.
"I think that would mop up a very large number of the disputed cases," he says.
Prof Paterson says he hopes the education secretary does that because it is looking at individual assessment.
"The problem last week was people weren't being assessed as individuals they were being assessed according to their school," he says. "That was grossly unfair."
Image source, gettySome young gymnasts in Scotland may have no club to return to once lockdown restrictions are lifted, the sport's leaders have warned.
Gymnastics facilities closed in March and are unlikely to be allowed to reopen until mid-September.
But Scottish Gymnastics fears the 20-week shutdown could have a long-term impact on the sport, with many clubs on the brink of a financial crisis.
The governing body is urging ministers to allow the sport to resume.
Justice Secretary Humza Yousaf tweets about claims a Celtic player failed to quarantine after returning from Spain and played in a game at the weekend.
After incidents of players visiting bars in Aberdeen, he asks if Scottish Football should continue.

Pupils in Shetland and the Borders in Scotland are returning to school today for the first time since March.
Although they are not required to wear face coverings, as you can see from these photos of pupils returning to Kelso High School, some have chosen to do so on their way in to class.
Physical distancing among students will not generally be required but hygiene and safety measures such as one-way systems have been put in place.

Image source, PA MediaMother-of-three Vicky Johnston says her daughter Charlotte had sat four Highers and expected four As. She got Bs.
She says she would have appealed against these grades but she is hoping that after Mr Swinney's announcement she won't have to.
Ms Johnston tells Radio Scotland this year's crisis should have taught us to move away from end-of -the-year exams and have continuous assessment so we know how pupils are doing at all times.
"Covid has been awful but we could say let's fix this this year and let's fix it for the kids going forward," she says.
Join us here for extensive coverage of the education secretary's statement which begins at 2.50pm this afternoon.

We still don't know what Education Secretary John Swinney will announce this afternoon but the expectation is that it will be a system which will place far more emphasis on the grades which teachers recommended to begin with.
Whether or not that means everybody gets the grades their teachers had put forward we will have to wait to find out.
If all students get the grade recommended by their teachers then the pass rate would rise significantly.
The problem with that could be the results given out this year could lack long-term credibility.
The aim of the SQA moderation had been to ensure the qualifications this year were just as valid as any other year.
Essentially what we are talking about is replacing one imperfect system with another.
Nothing that could have been arranged for this year, in this emergency would have been perfect.
