Havering College has been designated as a destination college for students wanting to enter the construction industry.
It was awarded Career College status in October by the Career Colleges Trust, an independent education body, for its range of construction and engineering courses, backed by a number of East London's biggest employers including developer L&Q.
The trust, formed in 2013 by former education secretary Lord Baker and two education charities, works with further education colleges and employers to create vocational curriculums, to help students gain employment soon after graduation.
Lord Baker attended the official launch event, joined by students and employers.
Asfa Sohail, vice principal at Havering College, said: "As a Career College, we will provide our learners with established, recognised and meaningful qualifications. With our strong focus on employer engagement, we are able to nurture a workforce that employers are really looking for."
In addition, full planning permission was granted for a £9.8 million Construction, Infrastructure, Skills and Innovation Centre (CISIC), where students will specialise in civil engineering, modern construction methods and modular building.
Lord Baker said: "Being part of the Career Colleges network will make a huge difference to students at CISIC, who will be equipped with real world skills - a benefit to them and UK construction."
A 3,000-home development in east London has been approved by City Hall.
