We present the Cosmic Evolution Early Release Science (CEERS) Survey, a 77.2 hour Director's Discretionary Early Release Science Program. CEERS demonstrates, tests, and validates efficient extragalactic surveys using coordinated, overlapping parallel observations with the JWST instrument suite, including NIRCam and MIRI imaging, NIRSpec low (R~100) and medium (R~1000) resolution spectroscopy, and NIRCam slitless grism (R~1500) spectroscopy. CEERS targets the Hubble Space Telescope-observed region of the Extended Groth Strip (EGS) field, supported by a rich set of multiwavelength data. CEERS facilitated immediate community science in both of the extragalactic core JWST science drivers ``First Light" and ``Galaxy Assembly," including: 1) The discovery and characterization of large samples of galaxies at z >~ 10 from ~90 arcmin^2 of NIRCam imaging, constraining their abundance and physical nature; 2) Deep spectra of >1000 galaxies, including dozens of galaxies at 6<z<10, enabling redshift measurements and constraints on the physical conditions of star-formation and black hole growth via line diagnostics; 3) Quantifying the first bulge, bar and disk structures at z>3; and 4) Characterizing galaxy mid-IR emission with MIRI to study dust-obscured star-formation and supermassive black hole growth at z~1-3. As a legacy product for the community, the CEERS team has provided several data releases, accompanied by detailed notes on the data reduction procedures and notebooks to aid in reproducibility. In addition to an overview of the survey and quality of the data, we provide science highlights from the first two years with CEERS data.

The Impact of Galaxy Overdensities and Ionized Bubbles on Ly$\alpha$ Emission at $z\sim7.0-8.5$
Strong Lyα emitters at z~7-8.5 are preferentially found in galaxy overdensities comparable in size to predicted ionized bubbles, with the EGS field showing evidence for an unusually large ionized sightline.

On The Very Bright Dropouts Selected Using the James Webb Space Telescope NIRCam Instrument
Very bright JWST dropout galaxies are mostly low-redshift dusty or old galaxies, with only a small fraction likely to be genuine ultra-luminous high-redshift galaxies.

Subaru meets JWST: A Direct Measurement of Ly$\boldsymbol{\alpha}$ Escape Fraction at $\boldsymbol{z\simeq6.2}$ with Dual Narrow-Band Imaging
Completeness-weighted stacking of 56 HAEs at z≃6.2 gives median f_esc^Lyα = 0.106^{+0.066}_{-0.044} with no strong Hα-luminosity dependence and UV-linked galaxy-to-galaxy trends.

Deep JWST spectroscopy of galaxies in a candidate ionized bubble at $z = 8.7$: probing reionization at pMpc scales with Ly$\alpha$ emission
Lyα transmission in the z=8.7 EGS volume is T_IGM=0.26+0.25−0.14, consistent with the field average and mildly inconsistent with a 2-pMpc ionized bubble, making such a bubble unlikely.

Discovery of Multiply Ionized Iron Emission Powered by an Active Galactic Nucleus in a z~7 Little Red Dot
The z=6.68 Little Red Dot THRILS 46403 shows a 4.5 sigma [FeVII] line, the first robust coronal-line detection among z>5 LRDs, plus narrow Balmer absorption, supporting an AGN with direct sightlines to gas at or beyon...

Exploring Cosmic Dawn with PANORAMIC I: The Bright End of the UVLF at $z\sim9 -17$
Bright galaxy number densities at z~10 match previous JWST results, but are lower at z~13, and the new z~17 upper limits imply a drop of at least a factor ~50 in UV luminosity density from z~10 to z~17.

Morphological Demographics of Galaxies at $z\sim 10-16$: Log-Normal Size Distribution and Exponential Profiles Consistent with the Disk Formation Scenario
Galaxies at z=10-16 have a log-normal size distribution with sigma 0.52, nearly uniform axis ratios, and exponential profiles, consistent with early disk formation.

Deep Spectroscopic Follow-Up of Maisie's Galaxy -- A Typical Galaxy in the Early Universe
Deep JWST spectroscopy of Maisie's Galaxy at z=11.4 reveals moderate star formation, metallicity, and ionization consistent with a typical galaxy on the early star-formation main sequence rather than an extreme source.
