Sec.  383.133  Testing methods.

    (a) All tests shall be constructed in such a way as to determine if

applicant wishes to obtain.
    (b) States shall develop their own specifications for the tests for 
each vehicle group and endorsement which must be at least as stringent 
as the Federal standards.
    (c) States shall determine specific methods for scoring the 
knowledge and skills tests.
    (d) Passing scores must meet those standards contained in Sec.  
383.135.
    (e) Knowledge and skills tests shall be based solely on the 
information contained in the driver manuals referred to in Sec.  
383.131(a).
    (f) Each knowledge test shall be valid and reliable so as to assure 
that driver applicants possess the knowledge required under Sec.

referred to in Sec.  383.111 for the applicable vehicle group, shall

brake knowledge. Each endorsement knowledge test, and the air brake 
component of the basic knowledge test as described in Sec.  383.111(g),

driver applicant's knowledge of the required subject matter with 
validity and reliability.
    (h) The skills tests shall have administrative procedures, designed 
to achieve interexaminer reliability, that are sufficient to ensure 
fairness of pass/fail rates.
