Carolyn Smith - a 34-year graduate of McKinley High School, Howard University and the first black woman to pass the District's examination for certified public accountant - is the new treasurer of the District of Columbia.

Smith's appointment to the $33,789-a-year position as the principal monitor of city intake and spending practices was announced this week by Kenneth Back, director of the D.C. Department of Finance and Revenue.

She replaces Charles L. Walker, who resigned the post in September after being arrested at Walter Reed Army Medical Center, where he was receiving free medical care by impersonating a retire colonel.

Walker later pleaded guilty to a misdemeanor charge and was sentenced to three months in jail.

Smith was formerly an audit manager for the private accounting firm of Coopers and Lybrand for eight years. She has also worked with the National Institute for Community Development, the United Planning Organization and the National Urban League.

Born in Lakewood, N.J., she passed the D.C. examination for CPA's in 1969. She is married, has two children and lives in northwest Washington.

Her appointment does not have to be confirmed.

In her new job, Smith will monitor the flow of city funds, oversee the disbursal of city money and be the person whose name will be signed to most city checks.
