You won’t be able to take the test from home, but you can now SCHEDULE a date for testing at a testing center online. Im pretty sure you will not be able to actually test from home as there are security requirements that need to be met by ALL testing centers. To be allowed to administer the test they must verify 2 forms of ID, and the address on ID must match a current utility bill.
The test center manager must also input his/her test center information noting he/she verified those items and to “release” a test for you to take. Also, testing rooms must be monitored by a person or video camera as to eliminate cheating. This is a FEDERAL license/certificate, so it is treated as such and security is still relevant.
