You can use the collect method
@crit_sections[:division] = Reference.find(:all,
:select =>
"refid,name",
:conditions => "ref_type = 'Division'",
:order =>
"name").collect { |r| [ r.refid, r.name ] }
I took the liberty of using a symbol for your hash key instead of a string.
Read up on symbols - in simplest terms, they are like strings without all
the string functionality, which we usually don't need anyway for hash keys.
