We present a measurement of the time-dependent $CP$-violating (CPV)
asymmetries in $B^{0}\to K_{s}^{0}\pi^{0}$ decays based on 124 million
$\Upsilon(4S)\to B\bar{B}$ decays collected with the BaBar detector at
the PEP-II asymmetric-energy $B$ Factory at SLAC. In a sample
containing $122\pm 16$ signal decays, we obtain the magnitude of the
direct CPV asymmetry $C_{K_{s}^{0}\pi^{0}} = 0.40^{+0.27}_{-0.28} \pm
0.09$ and the magnitude of the CPV asymmetry in the interference
between mixing and decay $S_{K_{s}^{0}\pi^{0}} = 0.48^{+0.38}_{-0.47}
\pm 0.06$ where the first error is statistical and the second
systematic.
