Art. 139. The oral exercises for those pupils who are candidates for the elementary teacher's certificate shall consist in answering nine questions on the three branches which shall be chosen by lot from among all the others constituting the general group of the studies of the elementary teacher; and for the candidates to the superior teacher's certificate, in the same exercise, and in like manner for all the branches studied in the four terms. Art. 140. After the termination of the written and oral exercises the practical exercise in needle-work will begin. This last having ended, the tribunal in the practice school shall be constituted, in the elementary or superior section, according to the class of the pupil in point. Each one of them shall draw a paper from an urn in which there shall be as many as there are branches of study included in the corresponding grade; that is to say, those studies of the elementary for the pupils of that class, and all the studies for the superior, except that of music and singing, which shall not form a part of this exercise. The subject having been chosen by lot, the one examined shall draw a new ticket from another urn from thirty prepared for that purpose. The number of that ticket shall indicate the point which she is to explain on the development of girls, the elementary spending ten minutes on the explanation and the superior fifteen. Art. 141. Immediately after the termination of an exercise, the exercise shall be passed upon by secret vote, for which purpose the president shall distribute to each one of the judges three tickets, one of which shall contain an S (sobresaliente [i.e., excellent]), the second one A (aprobada [i.e., passed]), and another one shall be blank (suspensa [i.e., conditioned]). Art. 142. If each one of the judges deposits a distinct letter in the urn the president shall declare the graduate to have passed; in other cases she shall be qualified according to the vote of the majority. Art. 143. In order to be admitted to the second exercise, one must have passed in the first; in order to be admitted to the third she must necessarily have passed in the second; and in order to be admitted to the fourth one must have passed the three preceding. Art. 144. Pupils conditioned in the exercises for confirmation shall not present themselves for new exercises until two months from the date of their condition. Art. 145. The exercises to which the preceding article refers can be repeated indefinitely, whenever the above-mentioned time intervenes between each two times. Art. 146. When a pupil repeats the exercises in which she shall have been conditioned, at least one of the judges who shall have participated in the condition shall form part of the tribunal.
