This brief review discusses the similarities between CP stars, focusing on magnetic fields and chemical abundances. New evidence for the presence of a magnetic field with a complex structure in some CP1 stars is presented. Small-scale structures on the surface of these stars may be connected with such a field, and the resulting effects on the curve-of-growth have been investigated. Finally, the changes during evolutionary time-scales on surface abundances are advocated as one possible reason of the large observed scatter in the chemical anomalies inside given groups of CP Stars.
