Identify skill gaps for a role.
Counting only the skills you have fully understates readiness, and counting partial skills as complete overstates it. Weighting partial skills at half gives a readiness figure that behaves sensibly, and the same weighting produces a gap score that reflects how much work remains. Multiplying by the time to close one skill converts a vague sense of not being ready into a number of weeks.
Weighted readiness and gap
Weighted held = full skills + partial x 0.5; readiness = weighted held / required x 100; weighted gap = missing + partial x 0.5; weeks = gap x weeks per skill
Around 60-70 percent of stated requirements is usually sufficient, because job advertisements describe an ideal rather than a threshold. Waiting for 100 percent means only applying for roles you have already outgrown.
The ones that appear in every advertisement for the role, not the ones easiest to learn. A skill listed as essential across the market is worth six weeks; one listed as desirable by a single employer usually is not.
Yes, if you can evidence them. A skill used on one project is legitimately claimable with that context, and it is much stronger than omitting it or overstating it as full expertise.
