Arkansas election officials say a proposal to raise the state's minimum wage needs at least 15,107 signatures from registered voters to qualify for the November ballot.
Secretary of State Mark Martin's office on Wednesday released the number of signatures the petitions needed for Give Arkansas a Raise Now to win a spot on the ballot.
Martin's office on Friday told the group it needed more signatures, but did not yet have an exact figure.
The group has been given until Aug. 18 to submit additional petitions.
The proposal would gradually raise Arkansas minimum wage from $6.25 an hour to $8.50 an hour by 2017.
