Parents can now access detailed GCSE data for every secondary school in England.
The Department for Education's Research and Statistics Gateway is designed to help families choose the right school for their children.
Previously the public could only find out the proportion of students gaining five or more A*-C GCSEs.
However, the new site breaks the data down, giving parents access to information relating to each GCSE subject.
"We live in an age when people expect more information, not less, in all areas of life. Our schools should be no different. For too long exam results in schools have been hidden," said education secretary Michael Gove.
"Parents have been desperate for more information on schools but too little has been available in the past. By publishing all this data we are giving parents the ability to choose the right school for their child."
The public can also use the site to see the proportion of students that are studying each component of the new English baccalaureate.
