Who is moving in the right direction?
It is easy to get stuck on snapshots — the municipality with the best merit value today, the municipality with the most certified teachers. But change is more telling: a municipality can have low absolute values but be steadily improving, while a top-ranked municipality slowly slides downward.
The chart ranks all municipalities by how much their merit value and teacher certification have changed over the past three to five years (depending on data availability). Municipalities improving on both dimensions end up at the top. Those declining on both end up at the bottom.
Composite score = change in merit value (points) + change in certification (percentage points x 2). The weighting reflects the fact that a one-percentage-point change in teacher certification historically correlates with roughly a 2-point change in merit value.
Note that trend movements are not causal — a positive trend can be due to demographic shifts, methodological changes or random variation. But consistent movements in the same direction over several years are a strong signal that something is genuinely changing.
