The Coherent Elastic Neutrino-Nucleus Scattering (CE$\nu$NS) has been observed at a 6.7-sigma confidence level by the COHERENT collaboration using a 14.6-kg CsI[Na] scintillator at Oak Ridge National Laboratory. The CE$\nu$NS process predicted by the standard model is a neutral-current weak interaction where the cross section is enhanced by $N^2$, where $N$ is the number of neutrons in the nucleus. This indicates a new way to build compact neutrino detectors and unlocks new channels to test the standard model. More detectors are being and will be deployed at Oak Ridge to further test CE$\nu$NS including a single-phase liquid argon detector, a p-type point contact germanium detector array and a NaI[Tl] detector array. The result, present status and future plans of the COHERENT collaboration will be presented.
