95 of 95 stops don't say whether a wheelchair user can board there. Riders who use wheelchairs can't plan a trip when accessibility is marked 'unknown'; apps show no information at all.

Set wheelchair_accessible on every trip (most small-agency fleets are 100% accessible, so this is often a single default).Likely your export tool
929 of 929 trips don't say whether the vehicle is wheelchair accessible. Even with accessible stops, riders need to know the bus itself can take them.
⏱ Often one default setting in your export.worth about +15 points
Agencies here usually clear this within about 1 week (based on 5 observed fixes).
Add fare_attributes.txt (or Fares v2 files) with your fare structure. If your service is fare-free, ask to have it marked fare-free instead.
The feed contains no fare information. Riders see 'fare unknown' in trip planners and can't budget their trip; visitors are most affected.

Service data covers the next 43 days.
0% of stops state wheelchair accessibility (0% marked accessible, 0% marked not accessible). This measures what the feed publishes, not whether a stop is physically usable. Fare data is not published.
0% of stops state accessibility (0% marked accessible). Reflects what the feed states, not verified physical usability.

Everything we checked
- Warning929 instances
929 of 929 trips don't say whether the vehicle is wheelchair accessible.
Even with accessible stops, riders need to know the bus itself can take them.
Fix: Set wheelchair_accessible on every trip (most small-agency fleets are 100% accessible, so this is often a single default). (Often one default setting in your export.)
Agencies here usually clear this within about 1 week (based on 5 observed fixes).

95 of 95 stops don't say whether a wheelchair user can board there.
Riders who use wheelchairs can't plan a trip when accessibility is marked 'unknown'; apps show no information at all.
Fix: Set wheelchair_boarding to 1 (accessible) or 2 (not accessible) for every stop. A field survey can start with the busiest stops. (A column in stops.txt; your scheduling software likely has it.)

Some service calendars in the feed have already expired.
Expired calendars are dead weight and can hide real schedule problems from your staff and vendors.
Fix: Remove past service periods the next time you export the feed. (One setting in most export tools.)
Agencies here usually clear this within about 1 week (based on 61 observed fixes).

The feed contains no fare information.
Riders see 'fare unknown' in trip planners and can't budget their trip; visitors are most affected.
Fix: Add fare_attributes.txt (or Fares v2 files) with your fare structure. If your service is fare-free, ask to have it marked fare-free instead. (A small file for most flat-fare systems.)

This feed models stations or entrances but has no pathways.txt.
Trip planners can't guide riders through the station, and there is no step-free route information for wheelchair users.
Fix: Add pathways.txt connecting entrances, platforms, and any elevators, with a level for each. (Worth it for multi-level or large stations; flat stops don't need it.)

Beyond the grade
Opportunities that do not change your grade today: fare detail, on-demand service, and deeper accessibility data.
3 route badge(s) pair a color and text color below the WCAG 4.5:1 contrast bar (31, 42, 51).
Consider: Adjust route_color or route_text_color so each pair clears 4.5:1. Often switching the text between black and white is enough.
47 stop name(s) use abbreviations or symbols a screen reader may mispronounce, with no spoken form set ("Dental on Elliott Dr", "Newton Rd - MERF", "Hancher/Park Rd", and more).
Consider: Add tts_stop_name with the spoken form, e.g. 'Main Street and Second Avenue', for the affected stops.
This feed models stations or entrances but has no pathways.txt and levels.txt.
Consider: Add pathways.txt connecting entrances, platforms, and elevators, and levels.txt for each floor, so the step-free route is described.

NTD certification readiness Ready
Published at a public URL, valid, and current: the three things the NTD GTFS requirement asks of a feed all hold here. Only your own D-10 certification makes that official; this is a heads-up, not a determination.
- Published Ready
- Published at a public URL.
- Valid Ready
- Passes validation with no errors.
- Current Ready
- Service data covers the next 43 days.
- agency_id matches your NTD ID Not checked yet
- Setting your GTFS agency_id to your five-digit NTD ID is an optional way to line a feed up with its National Transit Database record. FTA links the two on your P-50 form, so it is not a required feed change. We don't have your NTD ID on file, so this is not checked yet.
In plain words: if you report to the federal transit database, you have to publish a working, up-to-date feed and confirm it once a year. This box is a heads-up on whether yours looks ready; it is not the official sign-off.
A readiness signal mapping this feed to the FTA National Transit Database GTFS requirement (Report Year 2023 onward: a public, valid, current feed, certified annually on the D-10). Aligning agency_id with your NTD ID lets the feed line up with your NTD record; the July 2025 final rule links the two on the P-50 form rather than requiring that feed change, and requires shapes.txt in the published GTFS: Full Reporters from Report Year 2025, and Reduced, Rural, and Tribal Reporters from Report Year 2026. Not an official determination; your certification is the official check.
Conformance mark Not yet
This feed is close to the conformance mark. States wheelchair access on 0% of stops and 0% of trips; the mark needs 90% of each.
- Valid Met
- Passes validation with no errors.
- Current Met
- Service data covers the next 43 days.
- Accessible Not yet
- States wheelchair access on 0% of stops and 0% of trips; the mark needs 90% of each.
In plain words: earn this mark when your feed passes validation, has not expired, and says whether nearly every stop and trip is wheelchair accessible.
A pass credential for a feed that is valid, current, and states wheelchair access on nearly every stop and trip. Accessibility here measures what the feed publishes, not whether a stop is physically usable. How the conformance mark works.
Clears the Google and Apple Maps four-week coverage bar. This feed has 43 days of service ahead, clearing the four-week (28-day) window Maps asks for. No validator errors either, so riders keep seeing this agency in their trip planners; warnings lower the grade here but do not remove a feed from Maps.
How this agency maps to the standards
A data-quality lens, not a compliance determination. Each category shows this feed's score and the standards it relates to: the FTA National Transit Database GTFS requirement, the MobilityData grading scheme, and the Google Transit gate. Read the full standards crosswalk.
- Correctness 96 / 100
- GTFS Schedule best practices, checked by the MobilityData validator. MobilityData grading: stop locations, route names and colors. Google Transit: a feed must pass validation to stay in Maps.
- Freshness 72 / 100
- The FTA National Transit Database expectation of a valid, current feed. Google Transit: an expired calendar drops the agency from Maps.
- Rider experience 45 / 100
- GTFS Best Practices for rider-facing fields. MobilityData grading: stop names and headsigns.
- Realtime quality Not yet published
- GTFS-Realtime best practices: a stable URL, high uptime, and frequent updates.

The record below does not: it is the dated file this grade came from, published at https://gtfsscorecard.org/data/artifacts/university-of-iowa-cambus-cambus-197/2026-07-09.json and never overwritten, pinning the grade, category scores, rubric version, validator version, and the scored feed's sha256 as they stood on 2026-07-09.
