Uddingston Grammar was shocked last week by the sudden death of sixth year pupil Caitlin McCart.
Headteacher John McKay called a special assembly last Wednesday (October 23) to tell her year group that Caitlin has passed away in her sleep the previous night.
The pupils were offered the chance to spend time with the fully trained support team in the school who are skilled in dealing with bereavement as and when required.
A book of condolence was set up in the Old Parish Church and youngsters had the opportunity on Thursday to sign it, light a candle and have some quiet time to reflect together outside the school.
Mr McKay also wrote a letter to the whole school community informing them of what had happened.
He said: “Caitlin was a wonderful example of a modern young woman. She was vibrant, independent, enthusiastic and selfless.
“Caitlin’s star shone brightly and illuminated us all. We feel our loss intently however she shines on in our hearts.
“Our thoughts and prayers are with her family at this time.”
Caitlin’s friend Sophie Leung took to Twitter to pay tribute.
She said: “I love you and cannot believe you are gone. You will always be my best friend. No one will ever be as amazing as you were.”
Caitlin was keen on sports and played for the ladies’ team at Uddingston Hockey Club and was a youth coach.
As a mark of respect the club cancelled training on Thursday and the ladies’ match on Saturday. The gents’ teams held a minute’s silence before their games on Saturday as a mark of respect.
