(b)
Each school shall give an appropriate test to each
student who completes a unit of instruction as shown
in that school's approved curriculum.
(c)
A school may not graduate a student unless he has
completed all of the appropriate curriculum
requirements. However, the school may credit a
student with instruction or previous experience as
follows:
(1)
A school may credit a student with instruction
satisfactorily completed at—
(i)
An accredited university, college, junior college;

students who complete a comparable required
curriculum subject at the crediting school;
(ii)
By an evaluation of an authenticated transcript from
the student's former school; or
(iii) In the case of an applicant from a military
school, only on the basis of an entrance test.
(3)
A school may credit a student with previous aviation
maintenance experience comparable to required
curriculum subjects. It must determine the amount of
credit to be allowed by documents verifying that
experience, and by giving the student a test equal
to the one given to students who complete the
comparable required curriculum subject at the
school.
(4)
A school may credit a student seeking an additional
rating with previous satisfactory completion of the
general portion of an AMTS curriculum.
(d)
A school may not have more students enrolled than
the number stated in its application for a
certificate, unless it amends its application and
has it approved.
(e)
A school shall use an approved system for
determining final course grades and for recording
student attendance. The system must show hours of
absence allowed and show how the missed material
will be made available to the student.
(a)
Each certificated aviation maintenance technician
school shall keep a current record of each student
enrolled, showing—
(1)
His attendance, tests, and grades received on the
subjects required by this part;
(2)
The instruction credited to him under 147.31(c), if
any; and
(3)
The authenticated transcript of his grades from that
school.
It
shall retain the record for at least two years after
the end of the student's enrollment, and shall make
each record available for inspection by the
Administrator during that period.
(b)
Each school shall keep a current progress chart or
individual progress record for each of its students,
showing the practical projects or laboratory work
completed, or to be completed, by the student in
each subject.
(a)
Upon request, each certificated aviation maintenance
technician school shall provide a transcript of the
student's grades to each student who is graduated
from that school or who leaves it before being
graduated. An official of the school shall
authenticate the transcript. The transcript must
state the curriculum in which the student was
enrolled, whether the student satisfactorily
completed that curriculum, and the final grades the
student received.
(b)
Each school shall give a graduation certificate or
certificate of completion to each student that it
graduates. An official of the school shall
authenticate the certificate. The certificate must
show the date of graduation and the approved
curriculum title.
Each
certificated aviation maintenance technician school
shall, after certification or addition of a rating,
continue to provide the number of instructors
holding appropriate mechanic certificates and
ratings that the Administrator determines necessary
to provide adequate instruction to the students,
including at least one such instructor for each 25
students in each shop class. The school may continue
to provide specialized instructors who are not
certificated mechanics to teach mathematics,
physics, drawing, basic electricity, basic
hydraulics, and similar subjects.
(a)
Each certificated aviation maintenance technician
school shall provide facilities, equipment, and
material equal to the standards currently required
for the issue of the certificate and rating that it
holds.
(b)
A school may not make a substantial change in
facilities, equipment, or material that have been
approved for a particular curriculum, unless that
change is approved in advance.
(a)
Each certificated aviation maintenance technician
school shall adhere to its approved curriculum. With
AFRO-CAA approval, curriculum subjects may be taught
at levels exceeding those shown in appendix A of
this part.
(b)
A school may not change its approved curriculum
unless the change is approved in advance.
Each
certificated aviation maintenance technician school
shall provide instruction of such quality that, of
its graduates of a curriculum for each rating who
apply for a mechanic certificate or additional
rating within 60 days after they are graduated, the
percentage of those passing the applicable AFRO-CAA
written tests on their first attempt during any
period of 24 calendar months is at least the
percentage figured as follows:
(a)
For a school graduating fewer than 51 students
during that period—the national passing norm minus
the number 20.
(b)
For a school graduating at least 51, but fewer than
201, students during that period—the national
passing norm minus the number 15.
(c)
For a school graduating more than 200 students
during that period—the national passing norm minus
the number 10.
As
used in this section, “national passing norm” is the
number representing the percentage of all graduates
(of a curriculum for a particular rating) of all
certificated aviation maintenance technician schools
who apply for a mechanic certificate or additional
rating within 60 days after they are graduated and
pass the applicable AFRO-CAA written tests on their
first attempt during the period of 24 calendar
months described in this section.
Each
holder of an aviation maintenance technician school
certificate and ratings shall display them at a
place in the school that is normally accessible to
the public and is not obscured. The certificate must
be available for inspection by the Administrator.
The
holder of an aviation maintenance technician school
certificate may not make any change in the school's
location unless the change is approved in advance.
If the holder desires to change the location he
shall notify the Administrator, in writing, at least
30 days before the date the change is contemplated.
If he changes its location without approval, the
certificate is revoked.
The
Administrator may, at any time, inspect an aviation
maintenance technician school to determine its
compliance with this part. Such an inspection is
normally made once each six months to determine if
the school continues to meet the requirements under
which it was originally certificated. After such an
inspection is made, the school is notified, in
writing, of any deficiencies found during the
inspection. Other informal inspections may be made
from time to time.
(a)
A certificated aviation maintenance technician
school may not make any statement relating to itself
that is false or is designed to mislead any person
considering enrollment therein.
(b)
Whenever an aviation maintenance technician school
indicates in advertising that it is a certificated
school, it shall clearly distinguish between its
approved courses and those that are not approved.
