Training Effectiveness Score with knowledge retention score of 3.5 score: a worked example

Here is what the math looks like when conditions slip. We hold every other input steady and drop knowledge retention score to 3.5 score, then walk the calculation through step by step. Calculate a weighted training effectiveness score based on knowledge retention, on-the-job performance improvement, and business impact to prioritize training programs for improvement or investment.

The inputs for this scenario

  • Knowledge retention score (1-10): 3.5 score (the input this scenario stresses; the baseline uses 7)
  • On-the-job performance score (1-10): 6 score (held at the documented default)
  • Business impact score (1-10): 5 score (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Training effectiveness score = knowledge retention x 0.40 + performance improvement x 0.35 + business impact x 0.25.
  • Training effectiveness score works out to 4.75 score at these inputs, and this is the headline figure for the scenario.
  • Knowledge retention score works out to 3.5 score at these inputs.
  • On-the-job performance score works out to 6 score at these inputs.
  • Business impact score works out to 5 score at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where knowledge retention score sits at 7 score and the headline result is 6.15 score, this scenario comes in 22.76% below the baseline at 4.75 score.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to knowledge retention score, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. The inputs are subjective 1-10 ratings, so the score is only as reliable as the evidence behind each rating — calibrate scorers or it becomes opinion dressed as data.

Results at a glance

  • Training effectiveness score: 4.75 score (headline result)
  • Knowledge retention score: 3.5 score
  • On-the-job performance score: 6 score
  • Business impact score: 5 score
