How to say "preparedness" in Japanese

• 心構えこころがまえCommon
  noun, suru verbMental preparedness: the frame of mind one builds in advance of something important or trying, such as an exam or a big change. The default choice when 'preparedness' refers to a state of mind.
  何事なにごとが起おころうとも、彼女かのじょはそれに対たいする心構こころがまえが出来できている。↗

  Should anything arise, she will be prepared for it.
• 態勢たいせいJLPT N1approx.Common
  nounReadiness in an outward, organized sense: the posture or setup that a group, system, or side adopts in anticipation of action, as in emergency or defensive preparedness. Not a state of mind.
  ５００人にんの警官けいかんが厳重げんじゅうな警備けいび態勢たいせいおかれた。↗

  500 policemen were put on strict alert.
• 気構えきがまえCommon
  nounMental readiness again: the stance or attitude one takes up in facing a task or challenge. It overlaps heavily with 心構え, and either word usually works for this sense.
• 気持ちきもちJLPT N4approx.Common
  nounAt heart this word means feeling or mood, and it conveys preparedness only through phrases about having one's mind ready. For 'preparedness' itself it is seldom the word you want; prefer 心構え.

For mental readiness choose 「心構え」 or 「気構え」, for the organized readiness of a group or system choose 態勢, and treat 「気持ち」 as a marginal option that really means feeling or mood.
