We present combined Spitzer and Chandra observations of the nearby (~
260  pc) low mass star-forming region in the Serpens Cloud Core.  We
include observations from the IRAC and MIPS instruments onboard
Spitzer to view the region at infrared wavelengths from 3 to 70
microns.  These data allow us to detect thermal emission from
circumstellar disks and protostellar envelopes, and to classify stars
with disks and protostars using both colour-colour diagrams and
spectral energy distributions (SEDs).  These data are combined with
Chandra data to examine the effects of circumstellar disks on the
X-ray properties of the star.  The increased X-ray emission from
pre-Main Sequence stars also provides a method of identifying young
diskless stars in the cluster.  We have identified 138 young stellar
objects in Serpens, 62 of which are found to have X-ray emission
(45%);  20  Class I and 18 Flat Spectrum protostars, 62 Class II and
17 Transition disk young stellar objects, and 21 Class III Weak-Line T
Tauri stars.
