Base 2.2.4 of the Servicio Andaluz de Salud’s bases generales fixes the Celador/a exam’s shape in exact figures, and base 2.2.1.6 fixes a pass floor that is easy to misread as the pass mark. Here is what each number actually means.
How many questions are on the Celador/a SAS exam?
50 questions count toward your score, and you have 90 minutes to answer them. That comes from base 2.2.4 of the bases generales (Resolución de 22 de enero de 2025, BOJA núm. 17), which sets these figures for Grupo E categories, the group Celador/a falls into under the Estatuto de Personal no Sanitario. It is a cuestionario tipo test, one part of a concurso-oposición process in which the oposición phase and the concurso de méritos each carry half the final score.
The real paper is longer than 50 items, though. It also includes 3 preguntas de reserva, which exist only to replace a question the selection board annuls after the fact. If nothing on your paper gets annulled, and most papers have nothing annulled, you still answer exactly 50 questions for score. The reserve questions are there for fairness to the process, not extra material you need to prepare for as if it were part of the real 50.
How is the exam scored?
Every four wrong answers cancel the value of one correct answer, and blank answers cost nothing. The official formula is (A − E/4) × (100/P), where A is your correct answers, E is your wrong answers, and P is the number of questions that were not annulled (in practice, 50). Answering “I don’t know” by leaving a question blank is always safer than a random guess under this formula, since a blank contributes zero to both A and E while a wrong guess only starts costing you once you accumulate four of them.
What is the pass mark?
There is no single fixed percentage, which surprises a lot of candidates expecting one. Base 2.2.1.5 sets the real cut for turno libre at 60% of the average of the ten highest scores achieved in your own category that year, and 50% of that average for promoción interna. That number cannot exist until every candidate has sat the exam, so nobody can tell you the pass mark in advance.
What can be stated in advance is the floor underneath it: base 2.2.1.6 says no one passes with less than 40% of the maximum score, 40 of 100 points on the formula above, regardless of how the relative cut works out. That 40% floor is the only number knowable ahead of the sitting, which is why a mock exam has to use it as its pass line. Treat 40% as the legal minimum to even be in contention, not as a target: in a convocatoria with 1,225 plazas and far more applicants, the real relative cut in past years has typically landed well above the floor.
What does the selection process look like beyond the test?
The written test is the oposición phase, worth 50% of your final score; the other 50% comes from a concurso de méritos that scores things like prior experience and coursework, assessed separately from the multiple-choice paper. The oposición phase is eliminatory on its own: score below the cut described above and the méritos points never come into play. Applications go through the Ventanilla Electrónica de Profesionales, and paying the fee electronically gets a 10% discount.
What does a Celador/a SAS exam question actually look like?
The 19-tema Anexo XVII syllabus (BOJA 151, 2024) runs from the Spanish Constitution through hospital organisation and patient rights to specific procedures a celador performs on the ward. A practice bank built from that syllabus should be honest about gaps rather than papering over them: two temas, communication skills and patient movement and transfer, don’t have a citable public source precise enough to write verifiable test questions from, so a responsible pack states that rather than guessing at clinical procedure.

Knowing the mechanics of the formula only helps once you can answer enough questions correctly to clear the floor with room to spare, since the real cut tends to sit above it. Test Oposiciones España runs timed Celador/a SAS mocks on these exact figures, scores them with the same penalty formula, and cites the provision behind every answer so you can check it yourself.
