Three fundamentally different electronic structures for 3d electron states in LaCoO3, discussed in the current literature, have been presented. We are in favour of the localized electron atomic- like approach that yields the discrete energy spectrum associated with the atomic-like states of the Co3+ ions in contrary to the continouos energy spectrum yielded by band theories. In our atomic-like approach the d electrons form the highly-correlated system 3dn described by S=2 and L=2.
