  We have performed a survey for new members of the Upper Sco association that
have circumstellar disks using mid-infrared photometry from the Wide-field
Infrared Survey Explorer (WISE). Through optical and near-infrared
spectroscopy, we have confirmed 185 candidates as likely members of Upper Sco
with spectral types ranging from mid-K to M9. They comprise ~36% of the known
disk-bearing members of the association. We also have compiled all available
mid-infrared photometry from WISE and the Spitzer Space Telescope for the known
members of Upper Sco, resulting in a catalog of data for 1608 objects. We have
used these data to identify the members that exhibit excess emission from disks
and we have classified the evolutionary stages of those disks with criteria
similar to those applied in our previous studies of Taurus and Upper Sco. Among
484 members with excesses in at least one band (excluding five Be stars), we
classify 296 disks as full, 66 as evolved, 19 as transitional, 22 as evolved or
transitional, and 81 as evolved transitional or debris. Many of these disks
have not been previously reported, including 129 full disks and 50 disks that
are at more advanced evolutionary stages.
