Trend analysis for Wilby High School

Between 2016 and 2023, Wilby High School's Total Case Rate worsened from 1.9 to 9.1 recordable injuries per 100 full-time workers, a 366% increase across 7 years of OSHA reporting.

The safest year on record was 2020, at a TCR of 0.0, while 2019 saw the highest rate, at 15.6, a spread of 15.6 points between the best and worst reporting years. That's a wide swing relative to the establishment's overall rate, worth checking the year-by-year table below for whether a single severe year is driving the average, rather than a sustained trend.

Summed across those 8 reporting years, Wilby High School recorded 59 total injuries and illnesses, with no fatalities reported in any of those years. Readers comparing establishments should weigh the 8-year trend above alongside establishment size, since a larger workforce naturally accumulates more raw incidents even at a lower per-100-worker rate.

DART Rate, Transparent Calculation (2023)

What is the DART rate formula?

DART (Days Away, Restricted, or Transferred) is computed by OSHA as incidents × 200,000 ÷ hours worked. The 200,000-hour denominator equals roughly 100 full-time workers, which lets establishments of very different sizes be compared directly.

6 DART incidents × 200,000 ÷ 176,200 hours worked = 6.81 DART

Methodology: 29 CFR 1904, OSHA Form 300A recordkeeping
