In evaluating whether or not a clerkship will make you marketable, it is important to understand the differences between state and federal clerkships. These distinctions are examined below.
A. Federal Clerkships
Typically, the most prestigious clerkships have been those with federal judges. At top national law schools, students compete very aggressively for federal clerkships more so than they do for state judicial clerkships. Given the prestige of a federal clerkship, it can often make you marketable far beyond the geographic area where you are clerking.
At the federal level, the order of prestige of clerkships is typically (1) the Supreme Court, (2) circuit (appellate) clerkships, (3) federal district court (trial court) clerkships, and (4) clerkships with United States magistrates (who do a lot of the grunt work for federal district court judges). There are also several specialized courts (such as Federal Tax Court) that are of approximately the same prestige level as federal district court clerkships. For obvious reasons, clerking for the Chief Justice of the United States Supreme Court is generally considered the most prestigious clerkship there is. Similarly, a clerkship with a federal district judge in the Eastern District of New York is more prestigious than a clerkship with a federal district judge in Bay City, Michigan, for example, because there are far more people competing for clerkships in larger metro areas. Attorneys who clerk for the most prestigious judges are typically those whose marketability is likely to be increased as a result.
