a) The Neviim are read from in the synagogue (the Haftarot,
after the Torah is read)
b) Parts of the Ketuvim form part of the yearly prayer-cycle
(the five Megillot, plus many of the Psalms)
c) In general, all of the Neviim and Ketuvim are studied, since
they are an important part of the Torah (in the broader sense of
the word).
