The sub committee to be headed by Prime Minister's Economic Advisor Raghuram Rajan would be told to submit the report in a months time to decide which state qualifies, Chidambaram told reporters.
Asked about chance of Bihar being in the list, the Union minister said "Bihar will certainly qualify (on the new criteria of backwardness)".
Chidambaram, who in his budget speech had favoured changing criteria for deciding backwardness of a state for the purpose of giving special status, said "things are well on the move."
JD(U) has organised two big rallies, one in Patna (in November 2012) and another at Ramlila maidan Delhi in March last, in support of the demand. The CM, who has been pressing for special status as Bihar lags behind the national average on all important indices, has said it will be a major issue during the 2014 general elections.
He has also said that his party support for formation of a government at the centre after 2014 polls would depend on its view on giving special status to Bihar.
