Error Identification

Learn the CSE error-spotting format and a fixed scanning order (verb, pronoun, modifier, parallelism, diction) so you find the flaw fast or confidently declare no error.

Error identification is the CSE's efficiency test. A typical item shows a sentence with four or five lettered parts, or four full sentences, and asks either "Which part contains the error?" or "Which sentence has no error?" You are not asked to fix anything, only to find the flaw or certify its absence. Test-takers lose points here in two ways: they hunt randomly and run out of time, or they invent errors in correct sentences because "something sounds off." The cure for both is a fixed scanning order that checks the highest-frequency error types first, plus the discipline to accept "no error" when every check passes.

The two formats

Format 1: underlined parts. One sentence, four segments labeled A to D (sometimes with a fifth option, "No error"). Exactly one segment is wrong, or none is.

Example: "The committee, together with its consultants, (A) were tasked (B) to review the proposals (C) and to rank them (D) by cost." Segment A hides a subject-verb agreement error: the subject is the committee (singular); "together with its consultants" does not pluralize it. Were should be was.

Format 2: which sentence has an error / no error. Four complete sentences; pick the flawed one or the clean one. Read the instruction twice; picking the flawed sentence when the exam asked for the flawless one is a classic self-inflicted wound.

The five-point scanning order

Do not read for "feel." Scan for categories, in this order, because this order matches how often each error appears on civil service exams.

1. Verbs first. Check every verb for (a) agreement with its true subject and (b) tense form and consistency.

  • Strip the distractions: prepositional phrases (of the employees, with its consultants), as well as, together with, including. The real subject is what remains.
  • Agreement flags: each, every, either, neither, everyone (singular); a number of (plural) vs. the number of (singular); there is/there are (agree with what follows).
  • Tense flags: has/had + wrong participle (has went), unmotivated shifts (opened... takes), specific past time with present perfect.

2. Pronouns second. Check case, agreement, and reference.

  • Case: between you and me (object after preposition); she and I as subjects; whom after a preposition or as an object.
  • Agreement: "Each employee must submit their SALN" is flagged on the CSE; the safe form is his or her (or recast to plural: All employees... their).
  • Reference: a pronoun with two possible antecedents ("Liza told Ana that she was promoted") or none at all.

3. Modifiers third. Look at sentence openings and word placements.

  • Opening -ing/-ed phrase: is the noun after the comma the doer?
  • Limiters (only, almost, even): do they sit before the word they limit?
  • Adjective vs. adverb after the verb: linking verb takes adjective, action verb takes adverb.

4. Parallelism fourth. Any and/or series or correlative pair (not only/but also, either/or): column-check the joined elements.

5. Diction and idiom last. Confused words (affect/effect, its/it's, fewer/less), idiomatic prepositions (comply with, superior to, different from), and redundant expressions (return back, repeat again).

Worked example 1. "Neither of the applicants (A) have submitted (B) the notarized affidavit (C) that the examiner required (D) last week." Scan 1 (verbs): the subject is Neither, which is singular; "of the applicants" is a prepositional phrase. Have submitted should be has submitted. Error: A. One scan, done; no need to check B through D deeply, though a fast confirm never hurts.

Worked example 2. "Each of the drivers (A) was reminded (B) to renew their license (C) before the deadline (D) set by the LTO." Scan 1: was agrees with each; fine. Scan 2 (pronouns): their refers back to each (singular). The flagged segment is C, which should read his or her license. Error: C.

Worked example 3. Which sentence has NO error? (a) The data on regional enrollment were compiled by the planning unit. (b) Between the three field offices, Tarlac has the most vehicles. (c) The chief, as well as the deputies, were at the launch. (d) She is one of the employees who was cited for punctuality. Check (a): data as plural with were is standard formal usage, and the sentence passes all five scans. Check (b): between should be among for three offices. Check (c): as well as does not pluralize; were should be was. Check (d): who refers to employees (plural), so was should be were. Answer: (a).

The "no error" option: traps in both directions

When "No error" (or "no sentence has an error") is offered, two opposite traps operate.

Trap 1: inventing errors. Some correct constructions sound wrong to many test-takers:

  • "The data were analyzed" (formal plural data)
  • "If she were the chief" (subjunctive were)
  • "He lay on the cot for an hour" (correct past of lie)
  • "Everyone has submitted his or her form" (formal singular)
  • "The number of complaints has dropped" (the number = singular)
  • "It was they who requested the audit" (formal predicate nominative)
  • "Whoever arrives first should open the office" (whoever as subject of arrives)

If your only objection is "it sounds stiff," it is probably correct formal English. Formality is not an error.

Trap 2: missing the small flaw. Errors examiners hide in plain sight: a their after everyone, an apostrophe in it's used as a possessive, amount used for countables, a comma splice before however. These do not "sound" wrong at reading speed; only the category scan catches them.

Worked example 4. "The barangay captain, (A) whom residents say (B) is the most accessible official, (C) holds consultations (D) every Saturday." The tempting pick is A: many test-takers "correct" whom to who or vice versa on instinct. Test it: strip the insertion "residents say" and read the clause: ___ is the most accessible official. The pronoun is the subject of is, so it must be who, not whom. Error: A, and the reason is a rule, not a feeling.

Time management and process of elimination

Error-identification items are meant to take 30 to 45 seconds each. Budget your scan:

  1. Read the whole sentence once, normally, for meaning (5 seconds). Sometimes the error announces itself.
  2. Run the five-point scan on the underlined parts only (20 seconds). Non-underlined text is guaranteed correct; use it as your anchor. If the subject is not underlined, its number is fixed, and the underlined verb must match it.
  3. If two parts both look suspicious, ask which one breaks a nameable rule. On the CSE, one part breaks a rule; the other is merely awkward.
  4. If all scans pass, choose "no error" without guilt. On well-built exams, the no-error key appears a fair share of the time; refusing ever to pick it costs real points.

Common traps

  • Attractor nouns: a plural noun sitting between subject and verb ("The list of qualified bidders were posted"): the verb must match list, not bidders.
  • Inverted sentences: "Attached here is the copies" flips subject and verb; the subject copies demands are.
  • As well as / together with / including: these never change the subject's number.
  • Underline boundaries: the error must lie inside the underlined segment. If "their" is not underlined but "each employee" is, the fix belongs to the underlined part.
  • Instruction reversal: "Which sentence contains no error?" vs. "Which contains an error?" Underline the word no in your mind before answering.
  • Double errors that are really one: a comma splice around however may make two segments look wrong; the rule broken is one (punctuation with a conjunctive adverb).
  • Regional-idiom interference: expressions common in Philippine English conversation (cope up with, fill up a form, open the lights, result to) are flagged as errors in formal written English (cope with, fill out a form, turn on the lights, result in).

Exam strategy

  1. Memorize the scan order as a chant: verb, pronoun, modifier, parallel, word choice. Run it identically on every item so nothing depends on mood or luck.
  2. Find the subject-verb pair first even before looking at the letters; agreement is the single most-tested error.
  3. Justify your answer with a rule you can name. If you cannot name the rule, you have not found the error; keep scanning or pick no error.
  4. Never fix the un-underlined text in your head; it is the fixed frame the answer must fit.
  5. Practice with a timer. The scan feels slow for the first fifty items and becomes automatic afterward; speed comes from repetition of the same order, not from reading faster.

Error identification rewards the systematic. The examinee who checks the same five things in the same order beats the examinee with better "feel" almost every time.

Marking it done updates your Exam-Ready progress.
