Sunspot, the TMS was changed a bit about 3 years ago. Here is how the #4 Talk is handled.
km 10/03 p. 3 Theocratic Ministry School Schedule for 2004 ***ASSIGNMENT NO. 4: 5 minutes. The student should develop the assigned theme. When no references are indicated as source material, the student will need to gather material for this part by doing research in publications provided by the faithful and discreet slave class. When assigned to a brother, this part may be given as a talk with the Kingdom Hall audience in mind. When a sister is given this part, it should always be presented as outlined for Assignment No. 3. The school overseer may give a brother assignment No. 4 whenever he sees fit to do so. Please note that themes with asterisks next to them should always be assigned to brothers to develop as talks.
