The college was ranked 17th in a national league table published by The Sunday Times, matching the position it achieved in the same survey last year and college principal Martin Ward said it was 'great news'.
He said: "It is so pleasing to be placed so highly in a list which comprises some outstanding colleges.
"It is down to the exceptional hard work of our students and the outstanding efforts of our teaching staff.
"To be ranked in the top 20 sixth form colleges in the country for two consecutive years demonstrates a tremendous consistency in achievement, one that is mirrored in our excellent annual examination results.
"This accolade is great news not just for students and parents here in Shrewsbury, but from right across Shropshire too, and it reinforces our reputation for academic excellence."
Meanwhile, Shrewsbury and Atcham MP Daniel Kawczynski praised the hard work by staff and pupils.
He said: "I am delighted that Shrewsbury Sixth Form College has been recognised again by such a prestigious publication as The Sunday Times.
"I would like to extend my warmest congratulations to Martin Ward, his staff, and of course, the college's students, many of whom come from my constituency.
"This national recognition for the college is testament to the dedication and hard work of everyone involved."
More than 1,500 students aged between 16 and 19 attend Shrewsbury Sixth Form College, which has its main campus on Priory Road. The college will host a number of tours over the coming weeks.
