Why an official is not showing as eligible or available
Tell available (the calendar) apart from eligible (all assignment rules), then see why someone missed.
New Horizon Experience. This article describes the New Horizon Experience. In the Horizon WebRef mobile apps for Android and iOS, New Horizon is already what you see. On a computer or laptop, choose Try the New Horizon Experience from the banner or your account menu. You can switch back from that menu any time.
Both layouts are in use right now. In the Horizon WebRef mobile apps for Android and iOS you see the New Horizon Experience. On a computer or laptop, the older legacy layout stays until you choose Try the New Horizon Experience from the banner or your account menu. Match the steps to the screen in front of you. When a control or rule exists on only one layout, this article says so. The steps below start with the New Horizon Experience in the apps, then cover that older desktop or laptop layout.
This article is for assignors and organization administrators who open Assign on a game from Master Game Schedule. Officials who only work games do not open this window unless they also assign. Use it when someone you expect to schedule does not appear on the Eligible list.
Available versus eligible
Available means only the availability calendar. Eligible means the person qualifies for this game after all rules: rank, age, groups, block lists, site rules, and the calendar. Someone can be available and still not eligible. The calendar is one rule, not the whole answer.
New Horizon Experience
On Master Game Schedule, tap Assign on the game. Eligible and Ineligible buttons in the title bar show how many people are in each list. Switch to Ineligible to see people who do not qualify, with the full reason on the row (calendar, block list, rank, or another rule). Tap a why chip to open Eligibility details for the calendar window, block, ranking, or conflict that missed.
A color dot next to the name is availability only (green all day, amber limited, red unavailable, blue already scheduled). You can still assign someone who is not eligible. Horizon asks you to confirm, and the assignment is marked as an override.
When games are linked, eligibility is checked across the whole group (2 to 7 games). If the person is ineligible for one game in the group, they are ineligible for the set until you fix the miss or unlink the games. Positions must be named the same across the linked games to assign as a set.
If you still see the older legacy desktop or laptop layout
On desktop or laptop, assigning may still open in the older window until you choose Try the New Horizon Experience from the banner or your account menu. Open it from the Assign icon in the Action column. The list of people who qualify is labeled Eligible Officials. Choose Show Ineligible Officials in the top toolbar to see the rest. Open View Diagnostics (or the Diagnostics Table) from that toolbar to read the exact rule that missed.
To schedule someone who already declined the same game, use the Ineligible list and confirm the override. Linked games in that older layout still require the person to qualify for every game in the group. You can link 2 to 7 games.
