Happymomof3,
Please don't misunderstand or be led to believe that a communal penance service can be substituted for individual confession/absolution, except under extraordinarily unusual circumstances, which generally don't exist at communal penance services.
From the Catechism of the Catholic Church:
1415 Anyone who desires to receive Christ in Eucharistic communion must be in the state of grace. Anyone aware of having sinned mortally must not receive communion without having received absolution in the sacrament of penance.
1482 The sacrament of Penance can also take place in the framework of a communal celebration in which we prepare ourselves together for confession and give thanks together for the forgiveness received. Here, the personal confession of sins and individual absolution are inserted into a liturgy of the word of God with readings and a homily, an examination of conscience conducted in common, a communal request for forgiveness, the Our Father and a thanksgiving in common. This communal celebration expresses more clearly the ecclesial character of penance. However, regardless of its manner of celebration the sacrament of Penance is always, by its very nature, a liturgical action, and therefore an ecclesial and public action.
1483 In case of grave necessity recourse may be had to a communal celebration of reconciliation with general confession and general absolution. Grave necessity of this sort can arise when there is imminent danger of death without sufficient time for the priest or priests to hear each penitent's confession. Grave necessity can also exist when, given the number of penitents, there are not enough confessors to hear individual confessions properly in a reasonable time, so that the penitents through no fault of their own would be deprived of sacramental grace or Holy Communion for a long time. In this case, for the absolution to be valid the faithful must have the intention of individually confessing their grave sins in the time required. The diocesan bishop is the judge of whether or not the conditions required for general absolution exist. A large gathering of the faithful on the occasion of major feasts or pilgrimages does not constitute a case of grave necessity.
1484"Individual, integral confession and absolution remain the only ordinary way for the faithful to reconcile themselves with God and the Church, unless physical or moral impossibility excuses from this kind of confession." There are profound reasons for this. Christ is at work in each of the sacraments. He personally addresses every sinner: "My son, your sins are forgiven." He is the physician tending each one of the sick who need him to cure them. He raises them up and reintegrates them into fraternal communion. Personal confession is thus the form most expressive of reconciliation with God and with the Church.
1497 Individual and integral confession of grave sins followed by absolution remains the only ordinary means of reconciliation with God and with the Church.
And from the Code of Canon Law:
Can. 961 §1 General absolution, without prior individual confession, cannot be given to a number of penitents together, unless:
1° danger of death threatens and there is not time for the priest or priests to hear the confessions of the individual penitents;
2° there exists a grave necessity, that is, given the number of penitents, there are not enough confessors available properly to hear the individual confessions within an appropriate time, so that without fault of their own the penitents are deprived of the sacramental grace or of holy communion for a lengthy period of time. A sufficient necessity is not, however, considered to exist when confessors cannot be available merely because of a great gathering of penitents, such as can occur on some major feast day or pilgrimage.
§2 It is for the diocesan Bishop to judge whether the conditions required in §1, n. 2 are present; mindful of the criteria agreed with the other members of the Episcopal Conference, he can determine the cases of such necessity.
Can. 962 §1 For a member of Christ's faithful to benefit validly from a sacramental absolution given to a number of people simultaneously, it is required not only that he or she be properly disposed, but be also at the same time personally resolved to confess in due time each of the grave sins which cannot for the moment be thus confessed.
§2 Christ's faithful are to be instructed about the requirements set out in §1, as far as possible even on the occasion of general absolution being received. An exhortation that each person should make an act of contrition is to precede a general absolution, even in the case of danger of death if there is time.
Can. 963 Without prejudice to the obligation mentioned in can. 989, a person whose grave sins are forgiven by a general absolution, is as soon as possible, when the opportunity occurs, to make an individual confession before receiving another general absolution, unless a just reason intervenes.
Can. 964 §1 The proper place for hearing sacramental confessions is a church or oratory.
§2 As far as the confessional is concerned, norms are to be issued by the Episcopal Conference, with the proviso however that confessionals, which the faithful who so wish may freely use, are located in an open place, and fitted with a fixed grille between the penitent and the confessor.
§3 Except for a just reason, confessions are not to be heard elsewhere than in a confessional.
