With the increased sensitivity of gamma-ray detectors on the

Compton Gamma-Ray Observatory (CGRO) the number of

presently known gamma-ray pulsars has grown. The new detections

are beginning to provide clues to the origin of the high-energy

radiation in the form of emerging patterns and correlations among

observed quantities such as gamma-ray efficiency and spectral

index vs. age. But there are still many questions about the location

of the emission and its relation to the radio, optical and X-ray

pulses. This paper will review models for gamma-ray emission from

pulsars and will examine how well the detailed predictions of these

models account for the existing observations.
