Schools minister Jim Knight has announced that there will be a delay in the delivery of the advanced science diploma.
Those who are in teaching jobs
for 14 to 19-year-olds will have to wait an extra year before they can teach the most challenging of the three levels of the qualification.
While September 2011 will see the introduction of both the foundation and higher level science diploma, school staff
will have to wait until the following year to deliver the advanced option.
This is in an effort to ensure that the qualification gains the full backing of both higher education institutions and employers.
A group of experts are currently devising the science diploma to ensure that it meets the "highest possible" standards.
"The new science diploma needs to be the very best it can be to provide a significant boost to both participation and attainment in science - so we can't afford to rush it," stated Mr Knight.
Three times the number of students are expected to take the diploma this year than last year, the government stated recently.
