Prince Andrew took questions from the pupils at Rosebrook Primary
A Teesside school was given the royal seal of approval on Tuesday 13 July, after it was visited by HRH the Duke of York.
Prince Andrew officially opened Rosebrook Primary School in Stockton, during a visit to the region.
The state-of-the-art building replaced Roseworth and Redbrook schools, which amalgamated in 2008.
The Prince watched a musical performance and took questions before unveiling a plaque to mark its opening.
He wished the school "every success" and said he was sure will be outstanding.
Head teacher Val Rudd told BBC Tees Prince Andrew seemed to be "very impressed" with the building:
"He thought it was great, he said it truly was a 21st century building, he spoke to the architects and the builders themselves and really liked what he saw."
The Duke of York then moved on to Sedgefield to open the new Kromek headquarters.
The firm is best known for its pioneering work in airport security, including a scanner which can identify explosives, drugs or alcohol which are hidden in bottles of liquid.
Chief Executive Arnab Basu said it was a memorable day for all the staff:
"This is our workplace, this is where we come every day and do what we do and it was a great honour to welcome His Royal Highness."
"It is a great endorsement and a great morale boost for everyone."
"Every member of Kromek has worked very hard to get it where it is today and it is a recognition from the very highest level in the country."
