I hope you will excuse me for answering in English.

I was not planning to contribute to this question, having, as Pat says, written on the subject at inordinate length quite recently:

However, perhaps it would be helpful if I try once again to clarify the meaning of this extremely troublesome word "honours".

Before that, let me say that "licenciatura" should not be used here. A UK bachelor's degree (normally three years) has never really been equivalent to a licenciatura (five years), though before Bologna there was no real equivalent in Spain. Now, however, the grado is more or less equivalent, and that's certainly the right word.

On honours. We are dealing here with a university in England, and it is absolutely essential to start by ignoring the meaning of an "honours degree" in countries outside the United Kingdom. It has a different meaning in the United States, Canada and Australia. Indeed, we even have to ignore Scotland, where "honours degree" has a different meaning from England and Wales. Therefore, for example, the source Rosa has quoted, which does not apply at all to England and Wales, is irrelevant here. In E & W, an honours programme is not for the most advanced students; it is for practically 100% of all students.

Does "honours (degree) programme" actually mean anything different from just "(degree) programme"? Hardly at all. There is another kind of degree, called an "ordinary degree" or a "pass degree" (these terms are not always synonymous, but the difference need not concern us). In the past, before credits were introduced in the UK, an ordinary or pass degree was awarded to candidates who had almost but not quite failed the degree. It was always extremely rare. And no one was ever admitted to an "ordinary degree programme" on entering university; you could only be admitted to an honours programme.

Now that degrees consist of a certain number of credits, an honours degree is awarded if you complete the whole programme and gain 360 credits, even if you only just reach the pass mark. If you fail to pass all the course units, but gain a lesser number of credits (usually 300, which is the figure at the University of East London), then you can be awarded an ordinary degree. In some universities, though I don't think this is true of UEL, you can be transferred to an "ordinary degree programme" after the first year if it is clear that you are not capable of completing the full honours programme. If you gain even fewer than 300 credits you may be eligible for a Certificate in Higher Education or a Diploma in Higher Education, which are not degrees at all.

Here is confirmation from the course description of this precise degree:

"Programme Specification for BA (Hons) Psychosocial Studies [...]
Finally, students who do not wish or are unable to complete the whole programme can be awarded qualifications for the standard they have achieved. After the first year, students with six module passes (120 credits) may be awarded the Certificate of Higher Education (CertHE) and those with twelve module passes (240 credits) the Diploma of Higher Education (DipHE). Students with a total of fifteen module passes (300 credits) may be awarded an ordinary (unclassified) degree."

It is important to be clear that:
1. Ordinary (non-honours) degrees are very rare. I don't think national figures are available, but it is typically around 1-2% of students, virtually never more than 5%, and often none at all. In other words, over 95% of English and Welsh degrees, and often 100%, are honours degrees.
2. An honours degree is not more specialised than an ordinary degree. An ordinary degree involves the same course units; it's simply that you don't have to pass so many of them.

So then in England and Wales an honours degree is simply a full degree, and the word "honours" is almost meaningless.

It is therefore highly misleading to translate it as "con honores", which is used in the Spanish-speaking world to denote a degree of some distinction. I think "honours programme" should simply be translated as "programa de grado" or "plan de estudios de grado", and indeed "de grado" could be omitted, since it is really redundant. If the word "honours" is translated at all, then "con honores" should be put in inverted commas, and an explanatory note should be added to indicate that it simply means a full degree programme.

"Programme" could be either "programa" or "plan de estudios", in my opinion.

I repeat: no university in English and Wales actually admits students to any bachelor's degree programme other than an honours programme. A non-honours or ordinary programme simply consists of five-sixths (or thereabouts) of the modules in the standard honours programme. The same modules. There is no way any university is going to put on special modules for one or two students who cannot cope with the full programme. It would be completely unviable, and it is not done.
