Team GB are on track to finish fourth or higher at the London 2012 Olympics, a report issued on Thursday has said.
UK Sport, the body responsible for elite athlete performance, said in its new quarterly report that the team should outstrip their 2008 medal haul.
It gives 23 Olympic and Paralympic sports 'green' status - meaning Team GB is exceeding expectations.
This is the highest level of 'greens' since the organisation started its traffic light rating system.
UK Sport head Liz Nicholl said: "We absolutely believe we are on track for our high-level goal of top four in the Olympic medal table, second in the Paralympic medal table, and [winning] more medals across more sports.
"We take confidence from the number of greens. It is more than we have had before so that is telling us we are in a very good place.
"Overall we are in a really good place with 44 World Championship medals in Olympic disciplines this year and 73 in Paralympic disciplines."
Team GB's target is to better the 47 medals it achieved in Beijing and to finish above fifth in the overall medal table.
Britain's haul in Beijing, where 19 of the 47 medals were gold, was the best performance by the country since 1908.
The new report shows that 13 summer Olympic sports are currently rated as green, with 15 at amber - meaning they are on target - and none are rated red, denoting they are falling short.
Athletics has been moved into the green category, meaning that it is expected to do better than the four medals it took in China.
Judo and synchronised swimming have also been upgraded from amber to green.
Hugh Robertson, minister for sport and the Olympics, said: "These are enormously encouraging results which show the benefit of the increase in lottery funding made available by Government in May 2010.
"They put us in an excellent position as we move towards London 2012 and onto Rio 2016."
