What is the difference between the school safety audit and the school safety survey?

The school safety audit definition is explained in Virginia Code § 22.1-279.8:

"School safety audit" means a written assessment of the safety conditions in each public school to (i) identify and, if necessary, develop solutions for physical safety concerns, including building security issues and (ii) identify and evaluate any patterns of student safety concerns occurring on school property or at school-sponsored events. Solutions and responses shall include recommendations for structural adjustments, changes in school safety procedures, and revisions to the school board's standards for student conduct.

The Virginia Center for School and Campus Safety is legislatively tasked with developing a standardized report format for submission of this information.  See Virginia Code Section § 9.1-184:

The Virginia Center for School and Campus Safety shall develop a list of items to be reviewed and evaluated in the school safety audits required by this section. Such items shall include those incidents reported to school authorities pursuant to § 22.1-279.3:1.

The Virginia Center for School and Campus Safety shall prescribe a standardized report format for school safety audits, additional reporting criteria, and procedures for report submission, which may include instructions for electronic submission.

At the present time, the standardized format for submission of safety audit data as prescribed by the Virginia Center for School and Campus Safety is the Virginia School Safety Survey.  Any other “audit” processes that the division superintendent deem necessary can be collected and analyzed at the local level but need not be submitted to the Virginia Center for School and Campus Safety.
