We propose to complete the first comprehensive spectroscopic survey of young stellar objects associated with the Serpens Main cluster. Already we have obtained optical spectra for 27 Serpens objects with X- ray emission and for the 20 optically brightest objects in the field. Utilizing our deep CCD images of the region obtained last year, we have selected 142 candidate young stellar objects which form an unbiased extinction-limited sample. By observing objects with both blue and red grating settings, we can derive effective temperatures and constrain surface gravities for candidate young stars complete down to 0.5 M_sun with extinctions A_v≤ 4 mag. Using our BVR photometry, we can then derive bolometric luminosities and through comparisons with theoretical tracks and isochrones for young stars, ages and masses. When combined with recent X-ray and infrared surveys of the Serpens region, we will be able to assemble a complete census of young stars, reconstruct the star formation history, and begin investigations into the mass function of this young cluster.
