To form the perfect
passive, pluperfect passive and future perfect passive tense change the ‘-m’ ending of the supine to ‘-s’ to form the past participle.
For example:
voco, vocare, vocavi, vocatum (1) vocatus, -a, -um
Remember that a past participle must agree with word it modifies in gender, number and case and it declines like ‘bonus, -a, -um’ 
.
To form the future perfect passive tense use the past participle like the other tenses in this group, but with the future tense of the verb sum, esse, fui, -, ‘to be’.
For example
| Latin | English |
|---|---|
| vocatus, vocata, vocatum ero | I will have been called |
| vocatus, vocata, vocatum eris | you will have been called |
| vocatus, vocata, vocatum erit | he/she/it will have been called |
| vocati, vocate, vocata erimus | we will have been called |
| vocati, vocate, vocata eritis | you will have been called |
| vocati, vocate, vocata erunt | they will have been called |
