This question made me curious because, I have taught children making their first Confession for over 30 years. Here is what I found on wikipedia:
“A revised rite of the Sacrament of Reconciliation was given to the Church by Pope Paul VI on December 2, 1973. The new rite presents the sacrament in three different ritual forms:
The first form — The Rite for Reconciliation of Individual Penitents — is similar to the way most Roman Catholics remember “confession”; however, provision is made for the reading of sacred Scripture, and the penitent is given the option of speaking to the priest face-to-face or remaining anonymous (usually behind a screen). The priest may offer advice and gives a suitable penance. The priest pronounces absolution (the prayer for absolution was revised and extended) and the rite concludes with a short thanksgiving.[41]
The second form — The Rite of Reconciliation of Several Penitents with Individual Confession and Absolution — usually begins with readings from scripture, hymns, prayers, a homily and an examination of conscience, followed by a call to repentance. Private confession and reconciliation follow and a final thanksgiving, blessing and dismissal. Paul VI said in 1974 that he hoped this communal rite would “become the normal way of celebration.”
The third form — The Rite for Reconciliation of Several Penitents with General Confession and Absolution — is similar to the second, except that the penitents do not make an actual confession, but only manifest contrition (general confession). The prayer of absolution is given collectively or “generally” to all those gathered to celebrate the sacrament (general absolution). The penitents are obliged to actually confess each grave sin in their next confession.[42] Form three is intended for emergencies and other situations when it is not at all possible for the priest(s) to hear all the individual confessions. This rite has been discouraged for widespread use by the Vatican in many countries recently.”
When I started teaching in 1976, this new rite was being introduced in the US. Here is the link the a USCCB bulletin insert describing it:
