Hello geff70 and welcome to EduPhil.org.
Educational field trips are covered by DepEd Order No. 52, s. 2003, which is supplemental to DECS Order No. 56, s. 2001 and DepEd Order No. 51, s. 2002. DepEd Order No. 56, s. 2003, was reiterated in DepEd Order No. 87, s. 2003.
DepEd Order No. 56, s. 2001 explicitly stated,
Quote:3. Recognizing, however that such trips involve certain monetary costs which may be unaffordable to students coming from poor families and who therefore are not able to join, teachers should refrain from conducting tests based on these field trips. Should it be decided that tests will be held based on these field trips, students who were unable to join such trips should not be penalized; they shall be given special tests or assignments as substitutes for not joining the field trip.
The intent of this provision is clear: the student has an option not to join the field trip, for whatever the reason, including, but possibly not limited to, the monetary costs. Take note, however, that DepEd Order No. 56, s. 2001 was in reference to public schools.
In DepEd Order No. 52, s. 2003, there was an implicit inclusion of private schools, as indicated in the header of the order, which now includes "Heads, Public and Private Elementary and Secondary School Principals". In this order, it is stated that
Quote:f. As much as possible, field trips should not put an additional financial burden on the parents. Possible sponsors or other sources can be tapped for the purpose.
I am attaching DepEd Order No. 52, s. 2003 (which also includes the other two orders) in this post, so that you can look at the full text of the three orders yourself.
As far as I can discern from the two orders, it is obvious that a school, whether public or private, could not impose as compulsory to all students the collection of a fee for outings and field trips. That is the intent of the paragraph 3 in DepEd Order No. 56, s. 2001 (explicitly covers only public schools) and paragraph f in DepEd Order No. 52, s. 2003 (implicitly covers public and private schools). I was not able to locate any relevant jurisprudence on this though; what I would suggest is you talk to your school principal or school head, and show him a printout of these orders (plus my interpretation, if you want). If he/she refuses to bulge, you can raise the issue to the next higher authority, either to the school board (in a private school) or the District Head (for public schools).
Please do tell us the result of your actions, so that we can document cases like this, and we can guide others in the future. Thank you very much.
