How to use school discipline data.

What the field means

School discipline data records reported events or student counts from CRDC fields. These can include suspensions, expulsions, school arrests, and referrals to law enforcement. The fields are useful, but they require careful interpretation.

A raw count is not enough. Larger schools often have larger counts because they have more students. The right reading usually needs enrollment, subgroup context, source year, and the exact field definition.

Before you compare schools

• Check the source year. K12 Atlas uses CRDC SY 2021-22 for these fields.
• Separate event counts from student counts when the source defines them differently.
• Use enrollment denominators for rate context, especially when comparing schools of different sizes.
• Avoid causal claims. The page reports what was filed, not why it happened.

Reading example

A school with 40 suspensions and 2,000 students is different from a school with 40 suspensions and 200 students. The count is the same, but the context is not. A useful analysis keeps both the count and the denominator visible.

Discipline reporting can also vary by local practice, state policy, and recordkeeping. That does not make the field unusable. It means the field should be described as reported data and interpreted with source limits.

What the data cannot say

The data does not prove school climate, policy quality, or cause. It does not replace local records requests or qualitative reporting. It is a structured source field that can identify patterns worth checking.

How K12 Atlas uses it

K12 Atlas keeps discipline values tied to their source year and avoids converting them into a school label. The dataset is designed for users who need the facts, source links, and limits in one place.

The source-backed page

The matching data story is /data/discipline. It includes national counts, a public CSV slice, methodology notes, and Dataset JSON-LD.

Practical use cases

Advocates use discipline statistics to identify disparities in suspensions and referrals. Policy analysts use it to study school climate models. Journalists use citable counts to cover school policies.

Refresh and maintenance

This page updates biennially with the OCR CRDC release. Suspension counts, referral rates, and student demographics must remain linked to the specific collection year.
