The 15 Ghanaians all work with children and young people in the city of Bolgatanga and are taking part in a project known as Community Xchange, which saw a group of Plymouth workers travel to Ghana in February to shadow them and see how they work.
Conrad Balig, who works on a project providing education to street children in Bolgatanga, said the group had been overjoyed to meet their Plymouth counterparts again.
He said: "It's very exciting. We had a wonderful reception when we arrived at the train station. All our counterparts who came over to Bolgatanga were there, and our host families. It was an overwhelming scene.
"We arrived in the city like a football team that had won a trophy."
The 15 Ghanaian professionals will spend three weeks in Plymouth shadowing and working with their local counterparts.
Stephen Atelebe said: "I'm a teacher and I'm looking forward to seeing how the schools here compare to Ghana.
"Maybe I can learn things I can use in my classroom." Stephen will be working with history teacher Giles Isbell at Notre Dame School in Plymouth.
Giles said: "Stephen was such a wonderful host, it's good to be in a position to repay that."
The Community Xchange group were officially welcomed to Plymouth by Lord Mayor Ken Foster at a reception in the Council House organised by the Plymouth Ghana Link.
Cllr Foster told the group: "Plymouth is my home town and I hope you all feel completely at home here.
"In the three weeks you have here I hope you have the opportunity to learn something of our heritage, our culture, our sport and our leisure."
Cllr Foster then received the Ghanaian equivalent of the Freedom of the City from the honourable Yakubu Alhassan, the Bolgatanga municipal coordinating director, who has travelled to Plymouth with the 15 professionals.
As part of the welcome, Streetbeatz provided a dance demonstration and young singer-songwriter Josie Newton performed some of her songs.
Plymouth Ghana Link used the reception to launch a new website, which includes details of Ghana Week, a new event happening in July.
The website at www.plymouthghanalink.org
will showcase the activities of the link as well as providing project updates, a schedule of events, and details of how schools, faith groups, businesses and sporting institutions can get involved.
The site includes a draft programme of events and activities taking place during Ghana Week as well as information on the Community Xchange project, and is now up and running.
