NALP LCT common mistakes
NALP LCT · Understand the traps and how to avoid them.
Treating the LCT credential as a purely technical exam and skipping questions about apprenticeship, continuing education, and career-path requirements, guessing that any training option is acceptable.
Candidates come from field roles and assume the credential tests only horticultural knowledge; they do not study the professional-development framework and default to general impressions about how training is structured.
What to do instead
Build a short outline of the professional-development domain: how entry-level training, apprenticeship-style learning, and ongoing continuing education relate to the LCT credential. For each practice question, identify which stage of professional development it describes before choosing an answer.
Confusing the roles of industry associations, certification bodies, and employers, and selecting answers that attribute credentialing or standards-setting to the wrong organization.
The landscape industry has overlapping organizations, and candidates rely on vague memory of who does what rather than a clear map of responsibilities.
What to do instead
Make a one-page comparison table listing each type of organization (trade association, certifying body, employer, regulator) and its function. Practice sorting scenarios into the correct organization type until the distinctions are automatic.
Answering safety questions by choosing the most protective-sounding option without checking whether it matches the hierarchy of controls or the specific hazard described.
Candidates equate 'safest sounding' with 'correct' and do not apply a structured decision process, so they pick PPE over elimination or engineering controls even when the scenario calls for a higher-level control.
What to do instead
Memorize the hierarchy of controls in order (elimination, substitution, engineering controls, administrative controls, PPE). For every safety scenario, first name the hazard, then rank the controls, and only then read the answer choices.
Memorizing PPE lists without linking each item to its specific task, hazard, and inspection or replacement criteria, so scenario questions about when equipment must be removed from service are answered incorrectly.
Study guides often present PPE as a checklist, and candidates learn the list but not the conditions under which each item is required or rejected.
What to do instead
For each PPE category (eye, hearing, head, hand, foot, respiratory, high-visibility), write the task that triggers it, the hazard it addresses, and the defect that requires replacement. Practice with short scenarios that describe a damaged item and ask for the correct action.
Ignoring the reporting and documentation steps in incident scenarios and jumping straight to first aid or discipline, missing the answer that requires notification, investigation, or recordkeeping.
Candidates focus on the dramatic part of the scenario and forget that workplace-safety questions often test the administrative follow-up, not the immediate response alone.
What to do instead
Use a fixed incident-response sequence: secure the scene, provide care, notify the responsible person, preserve information, document, investigate, and correct. Run each practice scenario through the sequence and choose the answer that reflects the correct stage.
Calculating bid prices by adding a fixed markup to estimated costs without separating overhead, direct costs, and profit, and without accounting for labor burden.
Candidates without estimating experience treat markup and margin as interchangeable and forget that payroll taxes, insurance, and benefits raise the true cost of labor.
What to do instead
Practice building a bid in layers: direct materials, direct labor with burden, equipment, subcontractors, overhead allocation, then profit. Work numerical examples that convert between markup on cost and gross margin on price until the difference is clear.
Answering contract and client-relationship questions by choosing the option that avoids conflict in the short term, such as proceeding without written change orders or ignoring scope disputes.
Candidates value customer satisfaction and want to appear flexible, so they underestimate how documentation and contract terms protect both parties.
What to do instead
Study the purpose of written change orders, scope definitions, and payment terms. For each scenario, ask what protects the business and the client if the relationship later breaks down, and choose the answer that preserves a written record.
Treating design questions as purely aesthetic and ignoring site analysis, grading, drainage, and maintenance implications when selecting a design solution.
Candidates with installation backgrounds focus on how things look or how fast they can be built, and candidates from design backgrounds focus on appearance, so both miss the functional constraints the exam tests.
What to do instead
For every design scenario, run a checklist: client needs, site conditions, water movement, soil, access, plant selection, and long-term maintenance. Eliminate answer choices that ignore any of these constraints before choosing.
Answering installation and maintenance sequencing questions out of order, such as specifying planting before soil preparation or irrigation before grading is complete.
Candidates memorize individual tasks but not the dependencies between them, and exam scenarios deliberately present tasks in a jumbled order to test sequencing knowledge.
What to do instead
Write the standard sequence for each project type (site preparation, rough grading, utilities and irrigation, fine grading, planting, mulching, cleanup) and practice reordering scrambled task lists. Justify each step by what it depends on.
Managing the exam clock poorly by spending too long on calculation-heavy business questions and then rushing safety and professional-development questions that are quicker to answer correctly.
Candidates fear numerical questions and either over-invest in them or skip them entirely, without a plan for allocating time across domains.
What to do instead
Before the exam, set a target pace per question and decide a maximum time to spend on any calculation. Practice full-length timed sets that mix all four domains, and use a rule to flag and return to difficult items rather than stalling on them.
