The Arkansas Education Board has voted to not renew the charter of Dreamland Academy in Little Rock and to put Covenant Keepers College Preparatory Charter School on probation for a year.The board said Monday that an audit found that Dreamland Academy could not substantiate that its programs were helping the high-risk students enrolled there.The school's charter ends this month.The school had 144 students this year in kindergarten through fifth grade.Covenant Keepers had financial troubles and its director made an interest-bearing loan to cover rent payments -- a violation of state law.The school has since cleared up its finances but the matter was referred to state auditors and could be referred for prosecution.
