  The degree of top polarization and strength of $t\bar{t}$ correlation are
dependent on production dynamics, decay mechanism, and choice of the
observables. At the LHC, measurement of the top polarization and spin
correlations in $t\bar{t}$ production is possible through various observables
related to the angular distribution of decay leptons. A measurement of
differential distribution provides a precision test of the standard model of
particle physics and probes for deviations, which could be a sign of new
physics. In particular, the phase space for the super-symmetric partner of the
top quark can be constrained. Results from the Compact Muon Solenoid (CMS)
collaboration for top quark polarization and spin correlation in the dileptonic
channel are reviewed briefly in this proceeding. The measurements are obtained
using 19.5 fb$^{-1}$ of data collected in pp collisions at the center-of-mass
energy of 8 TeV.
