The rule as adopted simply eliminates three NAICS codes from exempt status in regards to filling out the OSHA 300 injury tracking log. 

NO LONGER EXEMPT:
NAICS 6111 (Elementary and Secondary Schools), 
NAICS 6116 (Other Schools of Instruction), and 
NAICS 6117 (Educational Support Services),

from the list of exempt industries in Table 1 of the rule, effective January 1, 2018. This means that the existing recordkeeping rules will apply to those industries from that date forward.
