(updated annually) for each competitive category by grade is
prepared by the Manpower Plans and Policy Division (CMC (MPP))
and approved by the Secretary of the Navy at least 30 days prior
to the convening date of a selection board. The plan serves as
a planning tool for the development of each selection board.
The plans contain selection opportunities, zone sizes, numbers
authorized to select, and any skill guidance for each grade and
competitive category. SECNAVINST 1420.1B provides specific
guidance on the requirements associated with promotion plans.
2. Factors. Planning factors that are taken into consideration
in developing the promotion plan are:
(a) The number of requirements needed to meet the projected
vacancies by grade.
(b) The estimated number of officers needed to fill
vacancies during the period in which it is anticipated that the
officers selected for promotion will be promoted and the number
of officers authorized by the Secretary of the Navy to serve in
the grade and competitive category under consideration.
(c) The impact of zone size and promotion opportunity on
time-in-service promotion flow points to the next higher grade.
(d) Critically short MOSs requiring skill guidance in the
precept.
(e) The forecasted attrition data based on an estimated loss
projection by grade, to meet a specified target determined two
fiscal years out.
3. Promotion Opportunity. The promotion opportunity is usually
a percentage based on the In-Zone population. The following
equations are used to determine selection opportunity:
