## Update a criterion

`client.Rubrics.Criteria.Update(ctx, rubricCriteriaID, params) (*RubricCriteriaResponse, error)`

**patch** `/v5/rubrics/{rubric_id}/criteria/{rubric_criteria_id}`

Apply a partial update to a criterion, creating a new version.

Updates are append-only: rather than overwriting the criterion in place, each
update inserts a new immutable version with an incremented version number, so
every prior state stays available through the versions endpoint. Fields not
supplied are carried forward from the current version. The request is rejected
if the criterion does not belong to the rubric named in the path.

### Parameters

- `rubricCriteriaID string`

- `params RubricCriterionUpdateParams`

  - `RubricID param.Field[string]`

    Path param

  - `Annotations param.Field[map[string, any]]`

    Body param: Free-form metadata for the Criteria

  - `Title param.Field[string]`

    Body param: The Criteria text

  - `Weight param.Field[float64]`

    Body param: Weight multiplier for scoring

### Returns

- `type RubricCriteriaResponse struct{…}`

  - `ID string`

  - `CreatedAt Time`

  - `RubricID string`

  - `Title string`

  - `Version int64`

  - `Annotations map[string, any]`

  - `Object RubricCriteriaResponseObject`

    - `const RubricCriteriaResponseObjectRubricCriteria RubricCriteriaResponseObject = "rubric_criteria"`

  - `Weight float64`

### Example

```go
package main

import (
  "context"

    option.WithAccountID("My Account ID"),
  )
  rubricCriteriaResponse, err := client.Rubrics.Criteria.Update(
    context.TODO(),
    "rubric_criteria_id",
    sgpdev.RubricCriterionUpdateParams{
      RubricID: "rubric_id",
